Subject: iio: accel: sca3000_core: avoid potentially uninitialized variable

The newly added __sca3000_get_base_freq function handles all valid
modes of the SCA3000_REG_ADDR_MODE register, but gcc notices
that any other value (i.e. 0x00) causes the base_freq variable to
not get initialized:

drivers/staging/iio/accel/sca3000_core.c: In function 'sca3000_write_raw':
drivers/staging/iio/accel/sca3000_core.c:527:23: error: 'base_freq' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This adds explicit error handling for unexpected register values,
to ensure this cannot happen.

Subject: iio:pressure: zpa2326: remove redundant "DEBUG" ifdef

The -Wempty-body gcc warning triggers in the newly added zpa2326 driver:

drivers/iio/pressure/zpa2326.c: In function 'zpa2326_dequeue_pressure':
drivers/iio/pressure/zpa2326.c:578:3: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]

The use of an empty statement behind 'if (...)' is harmless here, but
it shows that the dev_dbg() macro is not used correctly: when the "DEBUG"
macro is not set, dev_dbg() already defaults to a no-operation, though
one that lets the compiler know that the arguments are used, and lets
it check the format string.

Fixing this also simplifies the driver.

Subject: iio:trigger: Add helper function to verify that a trigger belongs to
 the same device

Some triggers can only be attached to the IIO device that corresponds to
the same physical device. Currently each driver that requires this
implements its own trigger validation function.

Introduce a new helper function called iio_trigger_validate_own_device()
that can be used to do this check. Having a common implementation avoids
code duplication and unnecessary boiler-plate code.

Add support for the AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1, AD7767-2
Analog to Digital converters. It's a family of single channel 24-bit SAR
ADCs. They are all digital interface compatible and the main difference is
the internal decimation rate and analog performance. For communication with
the host processor a SPI interface is used.

In addition the part has a data ready pin that is pulsed for one MCLK cycle
when a conversion has completed and can be used as a IIO trigger.

+* Texas Instruments LMP91000 potentiostat
+
+http://www.ti.com/lit/ds/symlink/lmp91000.pdf
+
+Required properties:
+
+  - compatible: should be "ti,lmp91000"
+  - reg: the I2C address of the device
+  - io-channels: the phandle of the iio provider
+
+  - ti,external-tia-resistor: if the property ti,tia-gain-ohm is not defined this
+    needs to be set to signal that an external resistor value is being used.
+
+Optional properties:
+
+  - ti,tia-gain-ohm: ohm value of the internal resistor for the transimpedance
+    amplifier. Must be 2750, 3500, 7000, 14000, 35000, 120000, or 350000 ohms.
+
+  - ti,rload-ohm: ohm value of the internal resistor load applied to the gas
+    sensor. Must be 10, 33, 50, or 100 (default) ohms.
+
+Example:
+
+lmp91000@48 {
+	compatible = "ti,lmp91000";
+	reg = <0x48>;
+	ti,tia-gain-ohm = <7500>;
+	ti,rload = <100>;
+	io-channels = <&adc>;
+};

Subject: staging: iio: isl29018: made error handling consistent

Changed the processing of IIO_CHAN_INFO_INT_TIME in isl29018_write_raw()
to unlock the mutex and return at the end of the function if invalid
input is passed in. This makes the error handling code consistent with
the processing of IIO_CHAN_INFO_CALIBSCALE and IIO_CHAN_INFO_SCALE
within the same function.

Subject: staging: iio: isl29018: fixed race condition in
 in_illuminance_scale_available_show()

in_illuminance_scale_available_show() references the
isl29018_chip->int_time variable in three places inside a for loop.
The value of the int_time variable can be updated by the
isl29018_set_integration_time() function, which is called by the
isl29018_write_raw() function. isl29018_write_raw() locks a
mutex specific to this driver when the integration time variable is
updated.

Subject: staging: iio: isl29018: change isl29018_read_raw() to only have one
 exit point

When the chip is in a suspended state, isl29018_read_raw() will return
-EBUSY. Change the function so that it only has a single exit point.

Subject: staging: iio: isl29018: check if the chip is in a suspended state

Add a check to isl29018_write_raw() to ensure that the chip is not in a
suspended state. This makes the code consistent with what is present
in isl29018_read_raw().

Subject: iio: pressure: Add driver for Honeywell ABP family

This patch adds minimal driver for the Honeywell Amplified Basic
Pressure sensors series. Sensors are pretty simple but are
available in many variants:
- psi/mbar/kPa output,
- analog/i2c/spi,
- gage/differential measurement,
- different measure ranges etc.

Refer to datasheets for more details:
http://sensing.honeywell.com/honeywell-sensing-basic-board-mount-pressure-sensors-abp-series-datasheet-323005128-c-en.pdf
http://sensing.honeywell.com/index.php%3Fci_id%3D45841

Driver internals:
- i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c
  bus doesn't support it, it is required to send a dummy byte to trigger
  measurement,
- since iio sysfs expects kilopascals, mbar-variants are treated as their
  respective kPa-s, hence i2c id-table has doubled entries in one line:
	{ "abp060mg", ABP006KG }, { "abp006kg", ABP006KG },
- psi-variants have prescaled values in config,
- no temperature reads yet.

Work remained:
- optional temperature channel,
- SPI support,
- DT binding.

Changes since v1:
- mutex is now locked in read_raw(),
- corrected error codes,
- fixed coding style issues,
- renamed few defines and functions abp -> abp060mg
(some structs left as they were to keep the sensible meaning).

Subject: iio: Implement counter channel type and info constants

Quadrature encoders, such as rotary encoders and linear encoders, are
devices which are capable of encoding the relative position and
direction of motion of a shaft. This patch introduces several IIO
constants for supporting quadrature encoder counter devices.

  IIO_COUNT: Current count (main data provided by the counter device)
  IIO_INDEX: Counter device index value

Subject: iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8

The ACCES 104-QUAD-8 is a general purpose quadrature encoder
counter/interface board. The 104-QUAD-8 is capable of monitoring the
outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit
dual-axis quadrature counter chips. Core functions handled by the
LS7266R1, such as direction and total count, are available.

Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and
also clears the counter's respective error flag. Although the counters
have a 25-bit range, only the lower 24 bits may be set, either directly
or via a counter's preset attribute. Interrupts are not supported by
this driver.

This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES
104-QUAD-4. The base port addresses for the devices may be configured
via the base array module parameter.

+Description:
+		Count mode for channel Y. Four count modes are available:
+		normal, range limit, non-recycle, and modulo-n. The preset value
+		for channel Y is used by the count mode where required.
+
+		Normal:
+			Counting is continuous in either direction.
+
+		Range Limit:
+			An upper or lower limit is set, mimicking limit switches
+			in the mechanical counterpart. The upper limit is set to
+			the preset value, while the lower limit is set to 0. The
+			counter freezes at count = preset when counting up, and
+			at count = 0 when counting down. At either of these
+			limits, the counting is resumed only when the count
+			direction is reversed.
+
+		Non-recycle:
+			Counter is disabled whenever a 24-bit count overflow or
+			underflow takes place. The counter is re-enabled when a
+			new count value is loaded to the counter via a preset
+			operation or write to raw.
+
+		Modulo-N:
+			A count boundary is set between 0 and the preset value.
+			The counter is reset to 0 at count = preset when
+			counting up, while the counter is set to the preset
+			value at count = 0 when counting down; the counter does
+			not freeze at the bundary points, but counts
+			continuously throughout.

+Description:

+		scale attribute selects the encoder phase division (scale of 1
+		selects full-cycle, scale of 0.5 selects half-cycle, scale of
+		0.25 selects quarter-cycle) processed by the channel Y counter.
+
+		Non-quadrature:
+			The filter and decoder circuit are bypassed. Encoder A
+			input serves as the count input and B as the UP/DOWN
+			direction control input, with B = 1 selecting UP Count
+			mode and B = 0 selecting Down Count mode.

Subject: Staging: iio: ad7150: constify attribute_group structures

Check for attribute_group structures that are only stored in the
event_attrs filed of iio_info structure. As the event_attrs field
of iio_info structures is constant, so these attribute_group
structures can also be declared constant.
Done using coccinelle:

Subject: staging: iio: ad7606: fix improper setting of oversampling pins

The oversampling ratio is controlled using the oversampling pins,
OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control
bit.

The gpio connected to the OS2 pin is not being set correctly, only OS0
and OS1 pins are being set. Fix the typo to allow proper control of the
oversampling pins.

Subject: staging: iio: ad7606: implement IIO_CHAN_INFO_OVERSAMPLING_RATIO

This driver predates the availability of IIO_CHAN_INFO_OVERSAMPLING_RATIO
attribute wherein usage has some advantages like it can be accessed by
in-kernel consumers as well as reduces the code size.

Therefore, use IIO_CHAN_INFO_OVERSAMPLING_RATIO to implement the
oversampling_ratio attribute instead of using IIO_DEVICE_ATTR() macro.

Move code from the functions associated with IIO_DEVICE_ATTR() into
the read_raw hook as well as add the write_raw hook with both masks set
to IIO_CHAN_INFO_OVERSAMPLING_RATIO.

From 598893e9cb64d9c74152db6174c4d7a6036a84e8 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Sat, 8 Oct 2016 14:34:25 +0200
Subject: iio: accel: Add driver for the MiraMEMS DA311 3-axis 12-bit digital
 accelerometer

This driver is based on the DA311 Android driver which can be found here:
https://git.matricom.net/Firmware/kernel_amlogic_meson-common/tree/1e70113a5befd07debb68f537156def84c5be57a/drivers/amlogic/input/sensor
the mir3da_* files are the DA311 driver.

Unfortunately there is no datasheet.

Subject: staging: iio: ad7192: implement IIO_CHAN_INFO_SAMP_FREQ

This driver predates the availability of IIO_CHAN_INFO_SAMP_FREQ
attribute wherein usage has some advantages like it can be accessed by
in-kernel consumers as well as reduces the code size.

Therefore, use IIO_CHAN_INFO_SAMP_FREQ to implement the
sampling_frequency attribute instead of using IIO_DEV_ATTR_SAMP_FREQ()
macro.

Move code from the functions associated with IIO_DEV_ATTR_SAMP_FREQ()
into respective read and write hooks with the mask set to
IIO_CHAN_INFO_SAMP_FREQ.

Subject: Staging: iio: meter: ade7758_core: implement IIO_CHAN_INFO_SAMP_FREQ

This driver predates the availability of IIO_CHAN_INFO_SAMP_FREQ attribute
wherein usage has some advantages like it can be accessed by in-kernel
consumers as well as reduces the code size.

Hence moving functionality from IIO_DEV_ATTR_SAMP_FREQ attribute into
IIO_CHAN_INFO_SAMP_FREQ handlers. Also Adding ade7758_read_raw() and
ade7758_write_raw() to allow reading/writing the element as well.

Date: Thu, 6 Oct 2016 11:07:44 +0300
Subject: Staging: sm750fb: fix do not add new typedefs warning

This patch fixes the checkpatch.pl warning: "WARNING: do not add new
typedefs". Hiding a variables of type 'struct' is not always a good
idea,because when we passing them as parameters we tempt to forget that
in this proces we work with  stack memory and allocatting struct on
stack is something that we should manage carefuly.

It is also delete the '_t' from the name of the structs and treat a line
over 80 character issue in ddk750_mode.c, that appear after my modification.

Subject: staging: lustre: obdclass: fix race during key quiescency

Upon umount, presumably of last device using same OSD back-end,
to prepare for module unload, lu_context_key_quiesce() is run to
remove all module's key reference in any context linked on
lu_context_remembered list.
Threads must protect against such transversal processing when
exiting from its context.

Date: Sun, 2 Oct 2016 22:27:58 -0400
Subject: staging: lustre: obdclass: Add synchro in lu_context_key_degister()

When unloading a module, it may happen that lu_context_key_degister()
removes a key while a thread is either registering it in a new
context (lu_context_init(), lu_context_refill()), or using it when
exiting from a context (lu_context__exit(), lu_context__fini()).

In these cases, we reference a key which no longer exists, and
the system crashes either because we use a *POISON'ed* pointer
in key_fini() -> key->lct_fini(), or because one of the following
assertions fails:
 - lu_context_key_degister():
        ASSERTION(cfs_atomic_read(&key->lct_used) == 1)
                  failed: key has instances: 2

 - lu_context_exit():
        ASSERTION(key != NULL)

 - key_fini():
        ASSERTION(atomic_read(&key->lct_used) > 1)

This can also leads to SLAB objects which are not freed:
        slab error in kmem_cache_destroy(): cache `echo_thread_kmem':
                   Can't free all objects

Note: ptlrpc service threads need to call lu_context_init/fini in
each loop (for each RPC), and this could be a big performance issue
on fat SMP machines if we add serialization by a spinlock and need
to lock/unlock it for multiple times for each RPC.

So the aim of this patch, which only impacts some low frequently used
functions, is:
  1) to add a synchronization in lu_context_key_quiesce(), also called
     by lu_context_key_degister(), to wait until all key::lct_init()
     methods have completed, by serializing with keys_fill()
  2) to add a synchronization in lu_context_key_degister(), to wait
     until all transient contexts referencing this key have run
     key::lct_fini() method

From f28f1a4581cbeaaa3098655761440fd2774e4abb Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:00 -0400
Subject: staging: lustre: obd: remove client Size on MDS support

Remove the unused OBD MD API method md_done_writing(). Remove the
unused logcookie and struct md_open_data ** parameters from
md_setattr(). Remove the unused functions iattr_from_obdo(),
md_from_obdo(), and obdo_refresh_inode().

From 1e1db2a97be57702fecd859efbe6e60fafc9b349 Mon Sep 17 00:00:00 2001
From: Jinshan Xiong <jinshan.xiong@intel.com>
Date: Sun, 2 Oct 2016 22:28:01 -0400
Subject: staging: lustre: clio: Revise read ahead implementation

In this implementation, read ahead will hold the underlying DLM lock
to add read ahead pages. A new cl_io operation cio_read_ahead() is
added for this purpose. It takes parameter cl_read_ahead{} so that
each layer can adjust it by their own requirements. For example, at
OSC layer, it will make sure the read ahead region is covered by a
LDLM lock; at the LOV layer, it will make sure that the region won't
cross stripe boundary.

Legacy callback cpo_is_under_lock() is removed.

Subject: staging: lustre: libcfs: shortcut to create CPT from NUMA topology

If user wants to create CPT table that can match numa topology,
she has to query cpu & numa topology, then provide a pattern
string to describe the topology, this is inconvenient.

To improve it, this patch can support shortcut expression "N" or "n"
to create CPT table from NUMA & CPU topology

From 872cbbdf1d6405fdb203e9d0038ac97cc99e3aff Mon Sep 17 00:00:00 2001
From: Gregoire Pichon <gregoire.pichon@bull.net>
Date: Sun, 2 Oct 2016 22:28:07 -0400
Subject: staging: lustre: ptlrpc: Add OBD_CONNECT_MULTIMODRPCS flag

The new OBD_CONNECT_MULTIMODRPCS connection flag indicates the support
of multiple modify RPCs in parallel. It can be specified by the client
within the connection request and by the server within the connection
reply. The new ocd_maxmodrpcs connection data specifies the maximum modify
RPCs in parallel supported by the server.

To allow the MDS to send the new ocd_maxmodrpcs field, it has been
required to modify RMF_CONNECT_DATA so that its size includes the new
field. This change leads to remove the ocd_connect_data_v1 structure.
Note that the client has been allocating an extra 16*sizeof(__u64) for
the obd_connect_data reply since 2.0 and even in later versions of 1.8)
so there is no problem for the MDS to just send the full reply size.

This patch fixes a bug in __req_capsule_get() since it wasn't checking
RMF_F_NO_SIZE_CHECK when receiving the message. This allows legacy
clients (with version lower that this commit) to send connection
request with ocd_connect_data structure size smaller (actually size is
ocd_connect_data_v1 structure size) than new server ocd_connect_data
structure size.

This patch also fixes a bug in the routine that displays the import's
connect data.

Date: Sun, 2 Oct 2016 22:28:09 -0400
Subject: staging: lustre: clio: use CIT_SETATTR for FSFILT_IOC_SETFLAGS

Add handling of inode flags to the handlers of CIT_SETATTR in lov and
osc. In the FSFILT_IOC_SETFLAGS case of ll_iocontrol() use
cl_setattr_ost() rather than obd_setattr_rqset() to set inode flags on
OST objects. Remove the then unused OBD API methods
obd_setattr_rqset() and obd_setattr_async() along with their
supporting functions.

From e33115e3371579ff1b4f8cd8300889d5b3ea8c49 Mon Sep 17 00:00:00 2001
From: Gregoire Pichon <gregoire.pichon@bull.net>
Date: Sun, 2 Oct 2016 22:28:10 -0400
Subject: staging: lustre: ptlrpc: Add a tag field to ptlrpc messages

The new tag field is used as a virtual index for multiple modifying
RPCs management. It is set by the client and allows the target to
release in-memory reply data when the tag is reused by a new RPC.

The tag field replaces the unused last_seen field of ptlrpcd_body
structure.

Additionally, the last_xid field is used to transfer the highest XID
for which a reply has been received and does not have an unreplied
lower-numbered XID.

Subject: staging: lustre: osc: fix bug when setting max_pages_per_rpc

After setting like "lctl set_param -P osc.*.max_pages_per_rpc", it
is possible that the function osc_obd_max_pages_per_rpc_seq_write
will be called before ocd_brw_size has been set when mount.
ocd_brw_size is meaningless when it is zero. So it should not be
the limit at that time.

Subject: staging: lustre: ldlm: Do not use cbpending for group locks

Currently, the CBPENDING flag is set on group locks when
the osc lock above them is released (osc_cancel_base).

This results in a situation where a new group lock request
on a resource does not match an existing group lock because
LDLM_FL_CBPENDING is set on the existing lock.

So two group locks are granted on the same resource, which
is not valid, since a given client can only have one group
lock on a particular resource.

Since group locks are manually released and not called back
like other LDLM locks, the CBPENDING flag doesn't make
sense. Since they must be manually released, they also
cannot go in the LDLM LRU cache and must be fully released
immediately once they are no longer in use.

This was previously accomplished by setting CBPENDING when
the corresponding osc lock is released, but as noted above,
this prevents the group lock matching some future lock
requests.

This patch uses the fact that group locks have an l_writers
reference which they keep until they are manually released,
so we remove them when they have no more reader or writer
references, without checking cbpending.

Subject: staging: lustre: ptlrpc: remove old protocol compatibility

Some old protocol compatibility workarounds are still present in
master that should have been removed when LUSTRE_MSG_MAGIC_V1 was.

In particular, the process for upgrading LUSTRE_MSG_MAGIC_V1 to
LUSTRE_MSG_MAGIC_V2 had the client to connect to the server with the
V1 protocol with op_flag=MSG_CONNECT_NEXT_VER set, and if the server
supported the V2 protocol it would reply with LUSTRE_MSG_MAGIC_V2.
This ensured that if the new client connected to an old server the
connection would be allowed.  However, even with V1 protocol support
removed, the 2.x clients are still connecting with NEXT_VER set.
In b1_8 this flag was contingent on LUSTRE_MSG_MAGIC_V1 being used,
which is how it should have been in 2.x as well.

A few other cleanups are be done at the same time:
 - disallow 1.8 clients (or at least those that don't understand
   OBD_CONNECT_FULL20) so we can remove workarounds for 1.8 clients
 - remove support for pre-2.1 DLM flock lock handling
 - don't workaround the lack of MDS_ATTR_xTIME_SET flags in setattr
 - always set MSGHDR_CKSUM_INCOMPAT18 (it can eventually be removed)

Subject: staging: lustre: llite: Report first encountered error

Failures in ll_ioc_copy_{start,end} are reported to coordinator.
The return code delivered to the caller should indicate what this
error was, not whether coordinator was successfully notified.

Subject: staging: lustre: mgc: MGC should retry for invalid import

After http://review.whamcloud.com/#/c/9967/ is landed, mgc does
not wait the import connected(state = FULL), then enqueue and
retrieve config log, which will cause the mount process to fail,
especially if the mgc is shared by multiple targets.
So once mgc enqueue is failed, it will give another chance to
wait the import to recover, if the import comes back in time,
it will try to enqueue again. Otherwise it will use local config log.

From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:20 -0400
Subject: staging: lustre: clio: add CIT_DATA_VERSION and remove
 IOC_LOV_GETINFO

During development a new api, cl_object_obd_info_get()
and cl_object_data_version() which then were later
replaced by a better solution CIT_DATA_VERSION. For
the case of the upstream client their is no point in
introducing a API to only have it removed later. Due
to the way the patches landed with their dependencies
it is not possible to separate out two patches. These
two combined patches do the following:

 * Add a new cl_io type CIT_DATA_VERSION to get file
   data version.
 * Remove the unused IOC_LOV_GETINFO ioctl.
 * Remove ll_glimpse_ioctl() and ll_lsm_getattr().
 * Remove the OBD API method obd_getattr_async().

From 55554f31e97878133d8b2bdf495504e1c557081c Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:21 -0400
Subject: staging: lustre: lov: add cl_object_layout_get()

Add cl_object_layout_get() to return the layout and generation of an
object. Replace some direct accesses to object LSM with calls to this
function.

In ll_getxattr() factor out the LOV xattr specific handling into a new
function ll_getxattr_lov() which calls cl_object_layout_get(). In
ll_listxattr() call ll_getxattr_lov() to determine if a lustre.lov
xattr should be emitted.  Add lov_lsm_pack() to generate LOV xattrs
from a LSM.

Remove the unused functions ccc_inode_lsm_{get,put}() and
lov_lsm_get().

Subject: staging: lustre: llite: add cl_object_maxbytes()

Add cl_object_maxbytes() to return the maximum supported size of a
cl_object. Remove the lli_maxbytes member from struct
ll_inode_info. Change the lsm_maxbytes member of struct lov_stripe_md
from __u64 to loff_t. Correct the computation of lsm_maxbytes in the
released layout case.

Subject: staging: lustre: hsm: make HSM modification requests replayable

There are several HSM requests which modify data on server and
reply on Lustre recovery, e.g. they should replay changes in
case of recovery.

Patch allows such requests to be replayed in recovery time and
they are issued from client using mdc_rpc_lock to serialize them
and avoid concurrent last_rcvd update on server.

Date: Sun, 2 Oct 2016 22:28:25 -0400
Subject: staging: lustre: ptlrpc: Move NRS structures out of lustre_net.h

NRS specific structures are not needed in the rest of the PtlRPC code.
It is more appropriate for these structures to be defined in a
separate header. This commit creates a lustre_nrs.h header for the
generic NRS structures, and policy-specific headers for the various
NRS policies.

From e57721e7244e64b9e930e8f17a001fa16d5e0b63 Mon Sep 17 00:00:00 2001
From: Niu Yawei <yawei.niu@intel.com>
Date: Sun, 2 Oct 2016 22:28:26 -0400
Subject: staging: lustre: quota: remove obsolete quota code

Remove the obsolete quotacheck, quotaon and quotaoff, which
were retained for the interoperability with old (< 2.4) client
and server.

Some other obsolete quota code related to LL_IOC_QUOTACTL_18,
Q_INVLIDATE and Q_FINVALIDATE are removed as well.

From 0a4bea92409b6846f0da7cb3b463629e8e4b7f92 Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:27 -0400
Subject: staging: lustre: obd: remove destroy cookie handling

Clients no longer need to track the max and default MDS cookiesizes
so remove
 the obsolete obod o_valid flag OBD_MD_FLCOOKIE,
 the struct client_obd members cl_{default,max}_mds_cookiesize,
 the struct obd_trans_info and parameters of this type,
 the cookiesize parameters from md_init_ea_size(),
 the files llite/*/{default,max}_cookiesize, and
 any code that needlessly handled these values.

From f648eed6f32410189f024c73fd86f3c6846c4b6a Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:29 -0400
Subject: staging: lustre: lov: use obd_get_info() to get def/max LOV EA sizes

Use obd_get_info() to get the default and maximum LOV EA sizes (along
with maximum cookiesize) from LOV. Remove the then unused function
obd_size_diskmd() and the unused get info key KEY_LOVDESC. When
computing the maximum LOV EA size use the active OST count
(ld_active_tgt_count) rather than the OST count (ld_tgt_count).

Subject: staging: lustre: ldlm: cancel aged locks for LRUR

It doesn't make sense to keep the very aged lock even with the
LRUR policy. This patch decreased the default ns_max_age from 10
hours to 65 minutes and changed LRUR policy to cancel very aged
locks.

Subject: staging: lustre: lov: copy_to_user uses wrong casting

With certain version of gcc lov_obd.c failes to compile
with the following warning.

In function copy_to_user,
inlined from lov_iocontrol at
lustre/lustre/lov/lov_obd.c:1168:
./arch/x86/include/asm/uaccess.h:735: error: call to
__copy_to_user_overflow declared with attribute warning:
copy_to_user() buffer size is not probably correct

In lov_iocontrol the data was being casted to int instead
of the required unsigned long. This patch changes the cast
to what is needed for copy_to_user.

From 48a2a12afc54aa1ebfdb1e821fc3dc7893816986 Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:35 -0400
Subject: staging: lustre: osc: remove remaining bits for capa support

With capa support removed from the OSC layer a few more bits
can be cleaned up. Convert the OBD getattr and setattr paths
to use struct obdo rather than struct obd_info. Remove
the oi_policy, oi_oa, and oi_capa members from struct obd_info.

From e10a431b3fd071bdbdea1ccb7aa2a9581f563deb Mon Sep 17 00:00:00 2001
From: "John L. Hammond" <john.hammond@intel.com>
Date: Sun, 2 Oct 2016 22:28:36 -0400
Subject: staging: lustre: lov: move LSM to LOV layer

Move the definition of struct lov_stripe_md along with supporting
functions from obd.h to lov_internal.h. Remove the unused functions
obd_packmd() and obd_free_diskmd(). Simplify lov_obd_packmd()
according to the reduced use cases and rename it lov_packmd().

is constant so the fields of rtllib_qos_parameters structure are

const struct v4l2_ioctl_ops *, so v4l2_ioctl_ops structures having this

Declare the structure usb_ep_ops as constant as it is only stored in the
ops field of a usb_ep structure which is a field of a nbu2ss_ep structure.
The ops field is of type const struct usb_ep_ops *, so usb_ep_ops
structures having this property can be decalared as const.

Subject: staging: most: aim-network: fix startup scenario.

In case the networking interface (running on MediaLB) is being started
before the MOST network is, it remains disabled even after the MOST network
has transitioned to active mode.

This patch removes the dependency on the MOST link status to keep the
networking queue active and the networking interface working for the
case described above.

Subject: staging: most: aim-network: setup mac address before ifup has
 finished

The networking AIM implements a non-standard behavior as it starts the
networking interface with an invalid MAC address and changes it by the time
a valid one is available.

This patch introduces a completion object to set the MAC address of the
networking interface before the .ndo_open callback (ifup) of the net_device
returns.

Subject: staging: most: hdm-usb: remove filtering of networking state

In case the networking interface goes down and up again, the USB HDM does
not report the state the MOST networking interface controller is in. This
might lead to nonfunctional network.

Since the networking AIM already takes care of hardware address checking
and tracing it can be removed from the HDM USB, which is what this patch is
doing.

Subject: staging: most: hdm-usb: fix mbo buffer leak

This patch fixes an MBO leak by replacing the proprietary
free_anchored_buffers() function with the usb_kill_anchored_urbs() function
of the USB subsystem and guarantees that the mbo->complete() completion
function is being called for each URB.

-* This file implements functions that correspond to the prism2/hfa384x
-* 802.11 MAC hardware and firmware host interface.
-*
-* The functions can be considered to represent several levels of
-* abstraction.  The lowest level functions are simply C-callable wrappers
-* around the register accesses.  The next higher level represents C-callable
-* prism2 API functions that match the Intersil documentation as closely
-* as is reasonable.  The next higher layer implements common sequences
-* of invocations of the API layer (e.g. write to bap, followed by cmd).
-*
-* Common sequences:
-* hfa384x_drvr_xxx	Highest level abstractions provided by the
-*			hfa384x code.  They are driver defined wrappers
-*			for common sequences.  These functions generally
-*			use the services of the lower levels.
-*
-* hfa384x_drvr_xxxconfig  An example of the drvr level abstraction. These
-*			functions are wrappers for the RID get/set
-*			sequence. They call copy_[to|from]_bap() and
-*			cmd_access(). These functions operate on the
-*			RIDs and buffers without validation. The caller
-*			is responsible for that.
-*
-* API wrapper functions:
-* hfa384x_cmd_xxx	functions that provide access to the f/w commands.
-*			The function arguments correspond to each command
-*			argument, even command arguments that get packed
-*			into single registers.  These functions _just_
-*			issue the command by setting the cmd/parm regs
-*			& reading the status/resp regs.  Additional
-*			activities required to fully use a command
-*			(read/write from/to bap, get/set int status etc.)
-*			are implemented separately.  Think of these as
-*			C-callable prism2 commands.
-*
-* Lowest Layer Functions:
-* hfa384x_docmd_xxx	These functions implement the sequence required
-*			to issue any prism2 command.  Primarily used by the
-*			hfa384x_cmd_xxx functions.
-*
-* hfa384x_bap_xxx	BAP read/write access functions.
-*			Note: we usually use BAP0 for non-interrupt context
-*			 and BAP1 for interrupt context.
-*
-* hfa384x_dl_xxx	download related functions.
-*
-* Driver State Issues:
-* Note that there are two pairs of functions that manage the
-* 'initialized' and 'running' states of the hw/MAC combo.  The four
-* functions are create(), destroy(), start(), and stop().  create()
-* sets up the data structures required to support the hfa384x_*
-* functions and destroy() cleans them up.  The start() function gets
-* the actual hardware running and enables the interrupts.  The stop()
-* function shuts the hardware down.  The sequence should be:
-* create()
-* start()
-*  .
-*  .  Do interesting things w/ the hardware
-*  .
-* stop()
-* destroy()
-*
-* Note that destroy() can be called without calling stop() first.

+ * Note that data records are expected to be sorted into
+ * ascending address order in the fw file.
+ *
+ * Note also that the start address record, originally an S7 record in
+ * the srec file, is expected in the fw file to be like a data record but
+ * with a certain address to make it identifiable.
+ *
+ * Here's the SREC format that the fw should have come from:
+ * S[37]nnaaaaaaaaddd...dddcc
+ *
+ *       nn - number of bytes starting with the address field
+ * aaaaaaaa - address in readable (or big endian) format
+ * dd....dd - 0-245 data bytes (two chars per byte)
+ *       cc - checksum
+ *
+ * The S7 record's (there should be only one) address value gets
+ * converted to an S3 record with address of 0xff400000, with the
+ * start address being stored as a 4 byte data word. That address is
+ * the start execution address used for RAM downloads.
+ *
+ * The S3 records have a collection of subformats indicated by the
+ * value of aaaaaaaa:
+ *   0xff000000 - Plug record, data field format:
+ *                xxxxxxxxaaaaaaaassssssss
+ *                x - PDR code number (little endian)
+ *                a - Address in load image to plug (little endian)
+ *                s - Length of plug data area (little endian)
+ *
+ *   0xff100000 - CRC16 generation record, data field format:
+ *                aaaaaaaassssssssbbbbbbbb
+ *                a - Start address for CRC calculation (little endian)
+ *                s - Length of data to  calculate over (little endian)
+ *                b - Boolean, true=write crc, false=don't write
+ *
+ *   0xff200000 - Info record, data field format:
+ *                ssssttttdd..dd
+ *                s - Size in words (little endian)
+ *                t - Info type (little endian), see #defines and
+ *                    struct s3inforec for details about types.
+ *                d - (s - 1) little endian words giving the contents of

-* This file declares the constants and types used in the interface
-* between a wlan driver and the user mode utilities.
-*
-* Notes:
-*  - Constant values are always in HOST byte order.  To assign
-*    values to multi-byte fields they _must_ be converted to
-*    ieee byte order.  To retrieve multi-byte values from incoming
-*    frames, they must be converted to host order.
-*
-*  - The len member of the frame structure does NOT!!! include
-*    the MAC CRC.  Therefore, the len field on rx'd frames should
-*    have 4 subtracted from it.
-*
-* All functions declared here are implemented in p80211.c
-*
-* The types, macros, and functions defined here are primarily
-* used for encoding and decoding management frames.  They are
-* designed to follow these patterns of use:
-*
-* DECODE:
-* 1) a frame of length len is received into buffer b
-* 2) using the hdr structure and macros, we determine the type
-* 3) an appropriate mgmt frame structure, mf, is allocated and zeroed
-* 4) mf.hdr = b
-*    mf.buf = b
-*    mf.len = len
-* 5) call mgmt_decode( mf )
-* 6) the frame field pointers in mf are now set.  Note that any
-*    multi-byte frame field values accessed using the frame field
-*    pointers are in ieee byte order and will have to be converted
-*    to host order.
-*
-* ENCODE:
-* 1) Library client allocates buffer space for maximum length
-*    frame of the desired type
-* 2) Library client allocates a mgmt frame structure, called mf,
-*    of the desired type
-* 3) Set the following:
-*    mf.type = <desired type>
-*    mf.buf = <allocated buffer address>
-* 4) call mgmt_encode( mf )
-* 5) all of the fixed field pointers and fixed length information element
-*    pointers in mf are now set to their respective locations in the
-*    allocated space (fortunately, all variable length information elements
-*    fall at the end of their respective frames).
-* 5a) The length field is set to include the last of the fixed and fixed
-*     length fields.  It may have to be updated for optional or variable
-*	length information elements.
-* 6) Optional and variable length information elements are special cases
-*    and must be handled individually by the client code.

+ * This file declares the constants and types used in the interface
+ * between a wlan driver and the user mode utilities.
+ *
+ * Notes:
+ *  - Constant values are always in HOST byte order.  To assign
+ *    values to multi-byte fields they _must_ be converted to
+ *    ieee byte order.  To retrieve multi-byte values from incoming
+ *    frames, they must be converted to host order.
+ *
+ *  - The len member of the frame structure does NOT!!! include
+ *    the MAC CRC.  Therefore, the len field on rx'd frames should
+ *    have 4 subtracted from it.
+ *
+ * All functions declared here are implemented in p80211.c
+ *
+ * The types, macros, and functions defined here are primarily
+ * used for encoding and decoding management frames.  They are
+ * designed to follow these patterns of use:
+ *
+ * DECODE:
+ * 1) a frame of length len is received into buffer b
+ * 2) using the hdr structure and macros, we determine the type
+ * 3) an appropriate mgmt frame structure, mf, is allocated and zeroed
+ * 4) mf.hdr = b
+ *    mf.buf = b
+ *    mf.len = len
+ * 5) call mgmt_decode( mf )
+ * 6) the frame field pointers in mf are now set.  Note that any
+ *    multi-byte frame field values accessed using the frame field
+ *    pointers are in ieee byte order and will have to be converted
+ *    to host order.
+ *
+ * ENCODE:
+ * 1) Library client allocates buffer space for maximum length
+ *    frame of the desired type
+ * 2) Library client allocates a mgmt frame structure, called mf,
+ *    of the desired type
+ * 3) Set the following:
+ *    mf.type = <desired type>
+ *    mf.buf = <allocated buffer address>
+ * 4) call mgmt_encode( mf )
+ * 5) all of the fixed field pointers and fixed length information element
+ *    pointers in mf are now set to their respective locations in the
+ *    allocated space (fortunately, all variable length information elements
+ *    fall at the end of their respective frames).
+ * 5a) The length field is set to include the last of the fixed and fixed
+ *     length fields.  It may have to be updated for optional or variable
+ *	length information elements.
+ * 6) Optional and variable length information elements are special cases
+ *    and must be handled individually by the client code.

You don't define a function prototype on one line as a #define, and then
the next declare it as an external C function, without expecting a C
compiler to complain loudly.

So fix up this mess.

Subject: staging: vc04_services: don't print pointers directly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kernel pointers should be printed with %pK and are not unsigned int big
on all architectures.  So fix this up to get rid of a bunch of warning
messages.

Note, there are other assumptions in this code that a pointer fits into
an int that need to be fixed up later.

From 9f8e0562e36693a60a2fd76c7a64184661eaea23 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Fri, 7 Oct 2016 10:24:57 -0700
Subject: staging: fbtft: Convert int arrays to s16

These arrays use -1, -2, and -3 as initiators for various types of
writes to initialize hardware.

No values are used that conflict with using these arrays as s16
instead of int and reducing overall data is good.

$ size drivers/staging/fbtft/built-in.o*
   text	   data	    bss	    dec	    hex	filename
 116120	  32872	   4152	 153144	  25638	drivers/staging/fbtft/built-in.o.new
 116104	  36344	   6200	 158648	  26bb8	drivers/staging/fbtft/built-in.o.old

Miscellaneous:

o Realign some of the arrays to make reading a bit easier

Subject: staging: comedi: make constants slightly more consistent

This makes INSN_CONFIG_DIO_{INPUT,OUTPUT,OPENDRAIN} simply be copies of the
already-existing constants COMEDI_INPUT, COMEDI_OUTPUT, and
COMEDI_OPENDRAIN.

This change also ensures that if a user happens to use, for example,
COMEDI_INPUT in place of where INSN_CONFIG_DIO_INPUT, the result will
always be the same and also acceptable and correct usage.

Subject: staging: comedi: ni_mio_common: split out ao arming from
 ni_ao_inttrig

AO device arming was previously done as a part of ni_ao_inttrig which is
called as a result of the user calling comedi_internal_trigger.  For
start_src == TRIG_EXT, this does not make very much sense since external
triggers should not conceptually need to be software triggered also.  This
patch splits out the arming functionality to allow arming to specifically
and separately be done via the CONFIG_INSN_ARM ioctl command.

In order to provide backwards compatibility, this patch also provides
automatic arming if ni_ao_inttrig is simply called.

Subject: staging: sm750fb: Merge ddk750_help.* into ddk750_chip.*.

The file ddk750_help.c contained only one function declaration,
so it was merged into ddk750_chip.c to simplify the driver.

Also, ddk750_help.h was merged into ddk750_chip.h to keep consistency.

With these changes a few global variables are removed and the function
ddk750_set_mmio is rewritten, so its purpose in the code is clearer.

Subject: Staging: wilc1000: Replace memcpy by ether_addr_copy

This patch fixes the following checkpatch.pl warning: Prefer

ether_addr_copy() over memcpy() if the Ethernet addresses are
__aligned(2)

According to ether_addr_copy() description and functionality, all
Ethernet addresses should align to the u16 datatype.

Here is the output of pahole for the relevant datastructures:
struct del_sta {
	u8                         mac_addr[6];          /*     0     6 */

	/* size: 6, cachelines: 1, members: 1 */
	/* last cacheline: 6 bytes */
};

struct sta_inactive_t {
	u8                         mac[6];               /*     0     6 */

	/* size: 6, cachelines: 1, members: 1 */
	/* last cacheline: 6 bytes */
};

gb_audio_manager_module_descriptor's cport field is actually used to
manage and pass interface id to user space.

Thus rename gb_audio_manager_module_descriptor's 'cport' field and
few other things to avoid confusion.

Subject: staging: wilc1000: Remove unnecessary extern variables.

Extern variables and functions used in only one file were removed
from .h files, and made static in the .c files they're used.

Extern variable wilc_initialized was declared and never used, so it was
removed.

Subject: staging: vt6656: Compress return logic into one line.

Compress the return logic into one line avoids unnecessary variable
declarations. In this case it also makes it easier to understand the
function.

Coccinelle was used to find this return statement. However, additional
compressions were done to make the function clearer.

Subject: staging: rtl8188eu: core: constify local structure

Constify the static struct RTW_CHANNEL_PLAN_MAP_REALTEK_DEFINE.

The only other instance was one of its properties being assigned to a
variable:
Index2G = RTW_CHANNEL_PLAN_MAP_REALTEK_DEFINE.Index2G;

Therefore this is a good candidate for constification.

Running size did not show any difference:
Before/After:
text    data     bss     dec     hex filename
44122     408    2974   47504    b990

Lastly, break up the long line to fix the checkpatch warning and conform
to kernel coding style.

Subject: staging: iio: cdc: ad7152: Implement IIO_CHAN_INFO_SAMP_FREQ
 attribute

Attributes that were once privately defined become standard with time
and hence a special global define is used. Hence update driver ad7152 to use
IIO_CHAN_INFO_SAMP_FREQ which is a global define instead of
IIO_DEV_ATTR_SAMP_FREQ.
Move functionality from IIO_DEV_ATTR_SAMP_FREQ attribute into
IIO_CHAN_INFO_SAMP_FREQ to implement the sampling_frequency attribute.
Modify ad7152_read_raw() and ad7152_write_raw() to allow reading and
writing the element as well. Also add a lock in the driver's private
data.

Subject: staging: iio: cdc: ad7746: implement IIO_CHAN_INFO_SAMP_FREQ

This driver predates the availability of IIO_CHAN_INFO_SAMP_FREQ
attribute wherein usage has some advantages like it can be accessed by
in-kernel consumers as well as reduces the code size.

Therefore, use IIO_CHAN_INFO_SAMP_FREQ to implement the
sampling_frequency attribute instead of using IIO_DEVICE_ATTR() macro.

Move code from the functions associated with IIO_DEVICE_ATTR() into
respective read and write hooks with the mask set to
IIO_CHAN_INFO_SAMP_FREQ.

Subject: staging: iio: cdc: ad7152: Replace mlock with a local mutex lock

mlock is intended to protect only switches between modes.
Given this driver doesn't support more than one mode (sysfs polled reads
only), replace mlock with a local mutex lock.

Subject: iio: bmi160_core: Fix sparse warning due to incorrect type in
 assignment

There is a type mismatch between the buffer which is of type s16 and the
samples stored, which are declared as __le16.

Fix the following sparse warning:
drivers/iio/imu/bmi160/bmi160_core.c:411:26: warning: incorrect type
in assignment (different base types)

drivers/iio/imu/bmi160/bmi160_core.c:411:26: expected signed short
[signed] [short] [explicitly-signed] <noident>
drivers/iio/imu/bmi160/bmi160_core.c:411:26: got restricted __le16
[addressable] [usertype] sample

This is a cosmetic-type patch since it does not alter code behaviour.
The le16 is going into a 16bit buf element, and is labelled as IIO_LE in the
channel buffer definition.

Subject: iio: ms65611_core: Fixes dereferencing regulator pointer

Change in handling of the regulator description means that static
checkers correctly assume we could be using dereferenced pointer to the
regulator. In reality we will never get the -ENODEV error, as current
behavior flow does not predict it, because:
If the device tree or board file does not define suitable regulators for
the component, it will be substituted by a dummy regulator, or, if
regulators are disabled altogether, by stubs.

Subject: iio: dac: mcp4725: use regulator framework

Use a standard framework to get the reference voltage. It is done that way
in the iio subsystem and it will simplify extending of the driver.

Structure mcp4725_platform_data is left undeleted because it used in the
next patch.

This change breaks the current users of the driver, but there is no
mainline user of struct mcp4725_platform_data.

Date: Sat, 8 Oct 2016 17:39:02 +0100
Subject: staging:iio:accel:sca3000 merge files into one.

In the early days of IIO we were much more inclined to keep the impact
of the core IIO elements to the minimum.  As time has moved on it has
become clear that hardly any builds are done without buffer support
and that it adds considerable complexity to the drivers.

Hence merge down the buffer and non buffer elements of the sca3000 driver
also allowing us to drop the header file used for the interfaces between
the two.

- * Free fall detection mode - supported but untested as I'm not droping my

- *
- * Unsupported as yet
- *
- * Time stamping of data from ring. Various ideas on how to do this but none
- * are remotely simple. Suggestions welcome.
- *
- * Individual enabling disabling of channels going into ring buffer
- *
- * Overflow handling (this is signaled for all but 8 bit ring buffer mode.)
- *
- * Motion detector using AND combinations of signals.
- *
- * Note: Be very careful about not touching an register bytes marked
- * as reserved on the data sheet. They really mean it as changing convents of
- * some will cause the device to lock up.
- *
- * Known issues - on rare occasions the interrupts lock up. Not sure why as yet.
- * Can probably alleviate this by reading the interrupt register on start, but

Subject: staging:iio:accel:sca3000 Fix clearing of flag + setting of size of
 scan.

Not clearing the stuff_to_read flag can lead to a false flag being set
on restarting the buffer if the data was not all read the previous time.

The size of the scan is needed to ensure the function
iio_buffer_read_first_n_outer actually tries to read the data.

This stuff has been broken for some time so not stable material.

Subject: staging:iio:accel:sca3000 move to hybrid hard / soft buffer design.

In a similar fashion to other newer drivers (e.g. ti_am335x), instead
of using the hardware buffer support in IIO to directly access the hardware
fifo, insert a software fifo and feed that from the hardware one when
interrupts occur.  This gives a simpler structure to the data flows and
allows more flexibility over how often data is shipped to userspace etc.

This was also the only direct user of the simplistic generalization found
in ring_hw.h so that header is removed.

Subject: staging:iio:accel:sca3000 use a 'fake' channel to handle freefall
 event registration.

This is an approach used in some newer drivers as it exposes the
compound channel events to the core rather than hiding their control
in sysfs attributes entirely via the driver.

From 9bc11d32b3a47e09904f954a3a17a514779afaec Mon Sep 17 00:00:00 2001
From: Jonathan Cameron <jic23@kernel.org>
Date: Sat, 8 Oct 2016 17:39:09 +0100
Subject: staging:iio:accel:sca3000 Clean up register defines.

Introduce some more masks and generally drive towards consistent naming.
Note the small indents used to indicate parts of registers + parts of
multiplexed registers.

Subject: staging:iio:accel:sca3000 Add write support to the low pass filter
 control

Also includes an available attribute.  The ordering of values appears
a bit random, but as the ABI doesn't specify this and we already have
both rising and falling lists I think this is fine.

Subject: staging:iio:accel:sca3000 Drop custom measurement mode attributes

This is now represented by the standard 3db filter frequency controls.
Things get complex wrt to the sampling frequency as these modes change
but that is fine under the IIO ABI where any value is allowed to effect
any other.

Subject: staging:iio:accel:sca3000 replace non standard revision attr with
 dev_info on probe

There seems little point in being able to query the part revision number
via sysfs.  Hence just put it in the kernel logs during probe incase
anyone ever wants to know.

Subject: staging:iio:accel:sca3000 Tidy up probe order to avoid a race.

Previously the device was exposed to userspace and in kernel consumers
before the interrupts had been configured. As nothing stopped them being
enabled in the interval this could cause unhandled interrupts.

Date: Sat, 15 Oct 2016 22:00:53 -0700
Subject: iio: light: ltr501: claim direct mode during select raw reads

Driver was checking for direct mode but not locking it.  Use
claim/release helper functions to guarantee the device stays
in direct mode during required raw read cases.

Subject: staging:iio:ad7606: Remove unused int_vref_mv field

Remove the int_vref_mv field from the ad7606_chip_info struct since the
field is never used by the driver. The value is also the same for all
derivatives of this chip, so if it will ever be used in the driver a
constant value will work just fine.

Subject: staging:iio:ad7606: Remove redundant name field from ad7606_chip_info

The name field in the ad7606_chip_info struct is set to the same value as
the as the name field in the corresponding {platform,spi}_device_id table
entry. Remove it from the ad7606_chip_info struct and pass the name from
the ID to the probe function. This slightly reduces the size of the
chip_info table and adding new entries requires less boilerplate.

Subject: staging:iio:ad7606: Remove default device configuration from platform
 data

While for some very selected setups it might be useful to be able to
provide default configuration data via the platform data, generally this
becomes very impractical as the number of configuration options increases.
So the general policy is to use the power-on default values of the device
and let the application using the device configure it according to its
needs.

Implement this scheme for the ad7606 driver by removing support for
specifying a default configuration via the platform data.

Subject: staging:iio:ad7606: Remove out-of-band error reporting

Currently the ad7606 driver prints a error message to the kernel log when
an application writes an invalid value to a sysfs attribute. While for
initial driver development and testing this might be useful it is quite
disadvantageous in a production environment. The write() call to the sysfs
attribute will already return an error if the value was invalid so the
application is aware that the operation failed. And generally speaking it
is impossible for an application to reliably match a log message in the
kernel log to a specific operation it performed, so the message becomes
just noise and might distract from more critical messages.

Subject: staging:iio:ad7606: Use oversampling ratio of 1 for no oversampling

Currently the ad7606 driver uses a value of 0 for the oversampling ratio to
express that no oversampling is done. Strictly speaking this means though
that no data capture is done at all. Instead change the driver to use a
value of 1, this is in accordance with what other drivers do and what the
IIO spec suggests.

Subject: staging:iio:ad7606: Avoid allocating buffer for each data capture

Currently the ad7606 driver dynamically allocates and frees a transfer
buffer each time a sample capture is performed in buffered mode, which
introduces unnecessary overhead. The driver state struct already contains a
buffer that is used for transfers in one-shot mode. This buffer is large
enough to hold all samples, but not the timestamp that might be present in
buffered mode. Extend the buffer size to be able to contain the timestamp
and update the buffered capture function to use this buffer.

Both the periodic buffer based and one-shot sysfs based capture methods
share a large portion of their code. Factor this out into a common helper
function.

Also provide a comment that better explains in more detail what is going on
in the capture function.

Subject: staging:iio:ad7606: Let the common probe function return int

The common probe function for the ad7606 currently returns a struct iio_dev
pointer. The returned value is not used by the individual driver probe
functions other than for error checking.

Let the common probe function return a int instead to report the error
value directly (or 0 on success). This allows to simplify the code.

Subject: staging:iio:ad7606: Let common remove function take a struct device *

Currently the common remove function takes a struct iio_dev *. This
parameter is retrieved by the individual driver remove functions by calling
get_drvdata() on their device. To simplify the code let the common remove
function directly take a struct dev * and do the IIO device in retrieval
the common remove function.

This also aligns the interface with the common probe function.

Subject: staging:iio:ad7606: Run trigger handler only once per trigger event

Currently the ad7606 driver installs the same function for the hard-irq and
threaded trigger handlers. This was introduced in commit 1caf7cb46135
("staging:iio:adc:ad7606 Convert to new channel registration method Update
Add missing call to iio_trigger_notify_done() Set pollfunc top and bottom
half handler"). Unfortunately the commit message does not mention why this
was done and Michael does not remember either.

Since the trigger handler function is idempotent (set a GPIO to 1) running
it twice does not do any harm, but is simply not necessary either. So set
the threaded trigger handler for the driver to NULL.

While we are at it also remove the function description comment that does
no say anything that can't be derived from the function name itself.

Subject: staging:iio:ad7606: Use GPIO descriptor API

Convert the ad7606 driver away from the deprecated legacy GPIO API and use
the new GPIO descriptor API.

This also means that the platform data struct is now empty and can be
removed.

From fa23105f85749923569a53139a1bb3465bba604d Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen <lars@metafoo.de>
Date: Wed, 19 Oct 2016 19:07:08 +0200
Subject: staging:iio:ad7606: Move buffer code to main source file

Currently the ad7606 buffer handling code resides in its own source file.
But this file contains only 4 small functions of which half are just
wrappers around other functions. Buffer support is also always enabled for
this driver, so move them over to the main source file. This reduces the
amount of boilerplate code.

Also rename the main function from ad7606_core.c to ad7606.c since there is
only a single file now.

Subject: staging: iio: ad7606: set proper supply name to devm_regulator_get()

The name passed to devm_regulator_get() should match the name of the
supply as specified in the device datasheet. The supply on this device
is called 'AVcc' while currently, the driver uses just 'vcc'.

Use 'avcc' to specify the supply voltage since it is custom to use the
lower-caps version of the datasheet name.

Subject: staging: iio: ad7606: rework regulator handling

Currently, this driver ignores all errors from regulator_get(). The way
it is now, it also breaks probe deferral (EPROBE_DEFER). The correct
behavior is to propagate the error to the upper layers so they can
handle it accordingly.

Rework the regulator handling so that it matches the standard behavior.
If the specific design uses a static always-on regulator and does not
explicitly specify it, regulator_get() will return the dummy regulator.

Subject: iio: dac: mcp4725: support voltage reference selection

MCP47x6 chip supports selection of a voltage reference (VDD, VREF buffered
or unbuffered). MCP4725 doesn't have this feature thus the eventual setting
is ignored and user is warned.

The setting is stored only in the volatile memory of the chip. You need to
manually store it to the EEPROM of the chip via 'store_eeprom' sysfs entry.

Date: Sat, 15 Oct 2016 11:04:37 -0700
Subject: iio: proximity: pulsedlight-lidar-lite-v2: cleanup power management

Remove pm_runtime_mark_last_busy() call that wasn't need in the probe
since the device should be put to sleep.

Clarification from Matt:
Basically it going to be suspended once pm_runtime_idle() is called,
and setting the last busy is useless and not needed.
Clearly this doesn't affect the device running but just makes the code
more consistent with other uses.

The dsb() macro for 32 arm compiles to dsb(sy) in the binary file.
This macro is no longer supported on arm64, so instead use dsb(sy)
which is completely binary compatible.

Subject: staging: vc04_services: Change fields of page list structure to fixed
 length

The arm processor core and the GPU have shared data structures.
One of these structures is a list of pages of data for messages.
This structure can not change since it is dependent on the GPU
firmware which is external to the kernel.  Convert the fields
of this structure to fixed length fields.

Subject: staging: vc04_services: Convert pointers in shared state to offsets

The arm processor core and the GPU have a shared data structure.
This structure contains pointers to base linux kernel objects such as
events.  The size of the pointer changes between 32 bit and 64 bit,
so it is necessary to convert these pointers to offsets from the
beginning of the state structure.

Luckly, the GPU does not interpret these pointers/offsets,
but this change is necessary to keep the structure the same since
the GPU code is outside the scope of the linux kernel
and can't be easily changed.

Subject: staging: vc04_services: Handle conversion from VCHIQ_SERVICE_HANDLE_T
 to VCHI_SERVICE_HANDLE_T

A VCHIQ_SERVICE_HANDLE_T which is an int is stuffed into a
VCHI_SERVICE_HANDLE_T which is a pointer, passed around, then
converted back to a VCHIQ_SERVICE_HANDLE_T. Since the data is
always actually a VCHIQ_SERVICE_HANDLE_T(int), never actually a
pointer, it is safe to simply cast the two back in forth.

Note that pointers are never stuffed into an int.

Subject: staging: greybus: audio: remove redundant slot field

gb_audio_manager_module_descriptor's intf_id field maintains the
information about the interface on which module is connected hence
having an extra slot field is redundant.

Thus remove the slot field and its associated code.

dgnc_tty_preinit() and dgnc_tty_post_uninit() functions are used to
allocate and free "dgnc_TmpWriteBuf" and this "dgnc_TmpWriteBuf" is
not really getting used. Hence remove these redundant functions.

Also remove dgnc_TmpWriteBuf variable as it is not used anymore.

Subject: staging: rtl8192x: fix bogus maybe-uninitialized warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The rtllib_rx_extract_addr() is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:

drivers/staging/rtl8192e/rtllib_rx.c: In function ‘rtllib_rx_InfraAdhoc’:
include/linux/etherdevice.h:316:61: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/rtl8192e/rtllib_rx.c:1318:5: note: ‘*((void *)&dst+4)’ was declared here
ded from /git/arm-soc/drivers/staging/rtl8192e/rtllib_rx.c:40:0:
include/linux/etherdevice.h:316:36: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/rtl8192e/rtllib_rx.c:1318:5: note: ‘dst’ was declared here

This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.

As the same warning appears in other files that have the exact
same code, I'm fixing it in both rtl8192e and rtl8192u, even
though I did not observe it for the latter.

Subject: staging: fsl-mc: add missing includes to fsl-mc-private.h

fsl-mc-private.h references several definitions that it does not explicitly
have includes for. Up until now we've gotten lucky due to include ordering
that things compile.  Add the missing includes.

Subject: staging: fsl-mc: dprc: shorten DPRC interrupt name

improve readibility of the DPRC interrupt name in sysfs by
shortening this and just using the device name.  There is only
one interrupt DPRC used, so no further differentiation is needed.

Subject: staging: fbtft: Fix module autoload

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/staging/fbtft/flexfb.ko | grep alias
$

After this patch:

$ modinfo drivers/staging/fbtft/flexfb.ko | grep alias
alias:          platform:flexpfb

After a recent bugfix, we get a warning about the use of an uninitialized
variable:

drivers/staging/lustre/lnet/libcfs/linux/linux-cpu.c: In function 'cfs_cpt_table_create_pattern':
drivers/staging/lustre/lnet/libcfs/linux/linux-cpu.c:833:7: error: 'str' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This part of the function used to not do anything as we would reassign
the 'str' pointer to something else right away, but now we pass an
uninitialized pointer into 'strchr', which can cause a kernel page fault
or worse.

Subject: staging/vchi: Add a TODO file of things I know we need to deal with.

I've left out the downstream HDMI audio driver from the "to be
imported" section, as we'll want to handle it natively in vc4.  The
downstream kernel will likely continue to use that driver for a while
due to using the interim "vc4 firmware KMS" mode while vc4 gets its
featureset (such as HDMI audio!) completed.

I've also left out VC-CMA, which appears to be about having Linux
manage a CMA area that the firmware gets to make allocations out of.
I'm not clear on if this is useful (the firmware's need for memory
drops massively with vc4 present, and may drop even more depending on
how we resolve dmabuf handling for camera and video decode)

+1) Port to aarch64
+
+This driver won't be very useful unless we also have it working on
+Raspberry Pi 3.  This requires, at least:
+
+  - Figure out an alternative to the dmac_map_area() hack.
+
+  - Decide what to use instead of dsb().
+
+  - Do something about (int) cast of bulk->data in
+    vchiq_bulk_transfer().
+
+    bulk->data is a bus address going across to the firmware.  We know
+    our bus addresses are <32bit.
+
+2) Write a DT binding doc and get the corresponding DT node merged to
+   bcm2835.
+
+This will let the driver probe when enabled.
+
+3) Import drivers using VCHI.
+
+VCHI is just a tool to let drivers talk to the firmware.  Here are
+some of the ones we want:
+
+  - vc_mem (https://github.com/raspberrypi/linux/blob/rpi-4.4.y/drivers/char/broadcom/vc_mem.c)
+
+  This driver is what the vcdbg userspace program uses to set up its
+  requests to the firmware, which are transmitted across VCHIQ.  vcdbg
+  is really useful for debugging firmware interactions.
+
+  - bcm2835-camera (https://github.com/raspberrypi/linux/tree/rpi-4.4.y/drivers/media/platform/bcm2835)
+
+  This driver will let us get images from the camera using the MMAL
+  protocol over VCHI.
+
+  - VCSM (https://github.com/raspberrypi/linux/tree/rpi-4.4.y/drivers/char/broadcom/vc_sm)
+
+  This driver is used for talking about regions of VC memory across
+  firmware protocols including VCHI.  We'll want to extend this driver
+  to manage these buffers as dmabufs so that we can zero-copy import
+  camera images into vc4 for rendering/display.
+
+4) Garbage-collect unused code
+
+One of the reasons this driver wasn't upstreamed previously was that
+there's a lot code that got built that's probably unnecessary these
+days.  Once we have the set of VCHI-using drivers we want in tree, we
+should be able to do a sweep of the code to see what's left that's
+unused.

Subject: staging: unisys: visorbus: visorchannel: Refactor locking code to be
 statically deterministic.

This patch makes locking in visorchannel_signalempty statically
deterministic.
As a result this patch fixes the sparse warning:
Context imbalance in 'visorchannel_signalempty' - different lock
contexts for basic block.

The logic of the locking code doesn't change but the layout of the
original code is "frowned upon"
according to mails on sparse context checking.
Refactoring removes the warning and makes the code more readable.

Subject: staging: iio: ad5933: avoid uninitialized variable in error case

The ad5933_i2c_read function returns an error code to indicate
whether it could read data or not. However ad5933_work() ignores
this return code and just accesses the data unconditionally,
which gets detected by gcc as a possible bug:

drivers/staging/iio/impedance-analyzer/ad5933.c: In function 'ad5933_work':
drivers/staging/iio/impedance-analyzer/ad5933.c:649:16: warning: 'status' may be used uninitialized in this function [-Wmaybe-uninitialized]

This adds minimal error handling so we only evaluate the
data if it was correctly read.

Subject: iio: gyro: Add driver for the MPU-3050 gyroscope

This adds a new driver for the Invensense MPU-3050 gyroscope.
This driver is based on information from the rough input driver
in drivers/input/misc/mpu3050.c and the scratch misc driver
posted by Nathan Royer in 2011. Some years have passed but this
is finally a fully-fledged driver for this gyroscope. It was
developed and tested on the Qualcomm APQ8060 Dragonboard.

The driver supports both raw and buffered input. It also
supports the internal trigger mechanism by registering a trigger
that can fire in response to the internal sample engine of the
component. In addition to reading out the gyroscope sensor
values, the driver also supports reading the temperature from
the sensor.

The driver currently only supports I2C but the MPU-3050 can
also be used from SPI, so the I2C portions are split in their
own file and we just use regmap to access all registers, so
it will be trivial to plug in SPI support if/when someone has
a system requiring this.

To conserve power, the driver utilizes the runtime PM
framework and will put the sensor in off mode and disable the
regulators when unused, after a timeout of 10 seconds.

The fullscale can be set for the sensor to 250, 500, 1000 or
2000 deg/s. This corresponds to scale values of rougly 0.000122,
0.000275, 0.000512 or 0.001068. By writing such values (or close
to these) into "in_anglevel_scale", the corresponding fullscale
can be chosen. It will default to 2000 deg/s (~35 rad/s).

The gyro component can have DC offsets on all axes. These can be
compensated using the standard sysfs ABI property
"in_anglevel_[xyz]_calibbias". This is in positive/negative
values of the raw values, so a suitable calibration bias can be
determined by userspace by reading the "in_anglevel_[xyz]_raw"
for a few iterations while holding the sensor still, create an
average integer, and writing the negative inverse of that into
"in_anglevel_[xyz]_calibbias". After this the hardware will
automatically subtract the bias, also when using buffered
readings.

Since the MPU-3050 has an outgoing I2C port it needs to act as
an I2C mux. This means that the device is switching I2C traffic
to devices beyond it. On my system this is the only way to reach
the accelerometer. The "sensor fusion" ability of the MPU-3050
to directly talk to the device on the outgoing I2C port is
currently not used by the driver, but it has code to allow I2C
traffic to pass through so that the Linux kernel can reach the
device on the other side with a kernel driver.

Example usage with the native trigger:

$ generic_buffer -a -c10 -n mpu3050

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As found by "gcc -Wmaybe-uninitialized", the latest change to the
driver lacked an initalization for the return code in one of the
added cases:

drivers/staging/iio/cdc/ad7746.c: In function ‘ad7746_read_raw’:
drivers/staging/iio/cdc/ad7746.c:655:2: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

This sets it to IIO_VAL_INT, which I think is what we want here.

Subject: iio: maxim_thermocouple: detect invalid storage size in read()

As found by gcc -Wmaybe-uninitialized, having a storage_bytes value other
than 2 or 4 will result in undefined behavior:

drivers/iio/temperature/maxim_thermocouple.c: In function 'maxim_thermocouple_read':
drivers/iio/temperature/maxim_thermocouple.c:141:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This probably cannot happen, but returning -EINVAL here is appropriate
and makes gcc happy and the code more robust.

Subject: iio: cros_ec_sensors_core: Add common functions for the ChromeOS EC
 Sensor Hub.

Add the core functions to be able to support the sensors attached behind
the ChromeOS Embedded Controller and used by other IIO cros-ec sensor
drivers.

The cros_ec_sensor_core driver matches with current driver in ChromeOS
4.4 tree, so it includes all the fixes at the moment. The support for
this driver was made by Gwendal Grignou. The original patch and all the
fixes has been squashed and rebased on top of mainline.

+What:		/sys/bus/iio/devices/iio:deviceX/calibrate
+Date:		July 2015
+KernelVersion:	4.7
+Contact:	linux-iio@vger.kernel.org
+Description:
+		Writing '1' will perform a FOC (Fast Online Calibration). The
+                corresponding calibration offsets can be read from *_calibbias
+                entries.

+What:		/sys/bus/iio/devices/iio:deviceX/location
+Date:		July 2015
+KernelVersion:	4.7
+Contact:	linux-iio@vger.kernel.org
+Description:
+		This attribute returns a string with the physical location where
+                the motion sensor is placed. For example, in a laptop a motion
+                sensor can be located on the base or on the lid. Current valid
+		values are 'base' and 'lid'.

This patch stops all started channels whenever the function most_nd_open
returns an error. Additionally, it renames variable wait_res to ret for
the consistency.

Subject: staging: most: hdm-usb: do h/w specific synchronization at
 configuration time

This patch puts the synchronization procedure trigger for asynchronous
channels into the function hdm_configure_channel. Likewise, it removes
triggering of hardware specific synchronization for other channel types
from the probe function as it is not required.

Subject: staging: fsl-mc: uprev binary interface to match MC v10.x

DPAA2 will not support MC firmware versions prior to MC v10.x.
Update the MC interface code and drivers to reflect this.
   -update the object .h files and code that builds commands to include
    the new command version in the command header
   -object versions are no longer available in the object attributes,
    so remove references to them and instead get the version from the
    new get_api_version() command
   -create/destroy commands for all objects have new arguments
   -dpmng_get_container_id() is replaced by dprc_get_container_id()

This supports a hardware ABI change and thus to match the new ABI
all the above changes need to happen in a single patch.

All MC firmware versions >= 10 will be supported going forward.

Subject: staging: vc04_services: Replace dmac_map_area with dmac_map_sg

The original arm implementation uses dmac_map_area which is not
portable.  Replace it with an architecture neutral version
which uses dma_map_sg.

As you can see that for larger page sizes, the dma_map_sg
implementation is faster then the original unportable dma_map_area
implementation.

Test                       dmac_map_area   dma_map_page dma_map_sg
vchiq_test -b 4 10000      51us/iter       76us/iter    76us
vchiq_test -b 8 10000      70us/iter       82us/iter    91us
vchiq_test -b 16 10000     94us/iter       118us/iter   121us
vchiq_test -b 32 10000     146us/iter      173us/iter   187us
vchiq_test -b 64 10000     263us/iter      328us/iter   299us
vchiq_test -b 128 10000    529us/iter      631us/iter   595us
vchiq_test -b 256 10000    2285us/iter     2275us/iter  2001us
vchiq_test -b 512 10000    4372us/iter     4616us/iter  4123us

For message sizes >= 64KB, dma_map_sg is faster then dma_map_page.

For message size >= 256KB, the dma_map_sg is the fastest
implementation.

"Normal" messages sizes should be about 1MB which is beyond
the length that this change shows a speed increase.

This is v2 of the patch which includes extra WARN_ONs and
incorporates feedback from Eric Anholt <eric@anholt.net>.

Subject: staging: sm750fb: Refine the code and remove unused code.

Every call to the function waitNextVerticalSync() used the macro
primaryWaitVerticalSync(), so the macro was removed and the function
waitNextVerticalSync() renamed to primary_wait_vertical_sync().

With this change, an unnecessary 'if' statement was removed together
with the lines within the 'else' statement, because it was never
satisfied.

The modified function was refined to better match the Kernel coding
style.

Subject: staging: vc04_services: use bcm2835 consequently

The naming bcm2708 is used only in the vendor kernel, so better
replace it with bcm2835 which is used in mainline in order
to avoid any confusion.

Subject: staging: lustre: osc: remove handling cl_avail_grant less than zero

Earlier cl_avail_grant was changed to an unsigned int. Juila
Lawall reported for the upstream client the following which
affects the Intel branch as well:

drivers/staging/lustre/lustre/osc/osc_request.c:1045:5-24: WARNING: Unsigned
expression compared with zero: cli -> cl_avail_grant < 0

Since cl_avail_grant can never be negative we can remove the
code handling the negative value case.

Subject: staging: lustre: obdclass: variable llog chunk size

Do not use fix LLOG_CHUNK_SIZE (8192 bytes), and
it will get the llog_chunk_size from llog_log_hdr.
Accordingly llog header will be variable too, so
we can enlarge the bitmap in the header, then
have more records in each llog file.

Subject: staging: lustre: lmv: allow cross-MDT rename and link

Remove checks for cross-MDT operation, so cross-MDT
rename and link will be allowed.

Remove obsolete locality parameters in MDT lock API after all of
cross-MDT operations are allowed.

This is the client side changed only so the upstream
client can support this.

From 8d69af0381930c9ab818cc3aa6bcf00bf328ed00 Mon Sep 17 00:00:00 2001
From: Amir Shehata <amir.shehata@intel.com>
Date: Thu, 27 Oct 2016 18:11:40 -0400
Subject: staging: lustre: ptlrpc: Introduce iovec to bulk descriptor

Added a union to ptlrpc_bulk_desc for KVEC and KIOV buffers.
bd_type has been changed to be a bit mask. Bits are set in
bd_type to specify {put,get}{source,sink}{kvec,kiov}
changed all instances in the code to access the union properly
ASSUMPTION: all current code only works with KIOV and new DNE code
to be added will introduce a different code path that uses IOVEC

As part of the implementation buffer operations are added
as callbacks to be defined by users of ptlrpc.  This enables
buffer users to define how to allocate and release buffers.

From: "John L. Hammond" <john.hammond@intel.com>
Date: Thu, 27 Oct 2016 18:11:41 -0400
Subject: staging: lustre: lov: remove LSM from struct lustre_md

In struct lustre_md replace the struct lov_stripe_md *lsm member with
an opaque struct lu_buf layout which holds the layout metadata
returned by the server. Refactor the LOV object initialization and
layout change code to accommodate this. Simplify lov_unpackmd() and
supporting functions according to the reduced number of use cases.

Subject: staging: lustre: clio: update file attributes after sync

This really only affects clients that are attached to lustre
server running ZFS, because zfs does not update # of blocks
until the blocks are flushed to disk.

This patch update file's blocks attribute after OST_SYNC completes.

Subject: staging: lustre: ptlrpc: embed highest XID in each request

Atomically assign XIDs and put request and sending list so
we can learn the lowest unreplied XID at any point.

This allows to embed in every resquests the highest XID for
which a reply has been received and does not have an unreplied
lower-numbered XID.

This will be used by the MDT target to release in-memory
reply data corresponding to XIDs of reply received by the client.

Subject: staging: lustre: llite: basic support of SELinux in CLIO

Bring the ability to properly initiate security context
on SELinux-enabled client and store it on server side via
extended attribute.

Security context initialization is not atomic, but that would
require a wire protocol change to send security label in the
creation request.

Filter out security.selinux from xattr cache as it is
already cached in system slab.

Subject: staging: lustre: ptlrpc: Do not resend req with allow_replay

If the request is allowed to be sent during recovery,
and it is not timeout yet, then we do not need to
resend it in the final stage of recovery.

Unnecessary resend will cause the bulk request to resend the
request with different mbit, but same xid, and on the remote
server side, it will drop such request with same xid, so it
will never get the bulk in this case.

Subject: staging: lustre: obdecho: don't copy lu_site

While creating an echo device, echo_device_alloc() copies the lu_site
from MD stack, such kind of copy result in uninitialized mutex and
other potential issues.

Instead of copying the lu_site, we'd use the lu_site by pointer directly.

Subject: staging: lustre: ldlm: reclaim granted locks defensively

It was discovered that to many ldlm locks where being
created on the server side to the point of memory
exhaustion. The work of LU-6529 introduced watermarks
to avoid this memory exhaustion. This is the client
side part of this work for the upstream client.

From d8389249f1ce4fe96c465f45dee1c848d71c06bc Mon Sep 17 00:00:00 2001
From: Sebastien Buisson <sebastien.buisson@bull.net>
Date: Thu, 27 Oct 2016 18:11:57 -0400
Subject: staging: lustre: ptlrpc: do not sleep if encpool reached max capacity

When encryption is enabled RPCs are encrypted just before being
sent. The encryption requires allocating memory in the encoding pool.
The current implementation in sptlrpc_enc_pool_get_pages() is
deadlock-prone. Indeed, if there is no more free pages in the pool,
all ptlrpcd threads can end up waiting in a queue, so there is no
thread available to process other requests. It means client is not
able to process replies from servers that yet contain last committed
transno useful to release memory allocated by previous requests,
including enc_pool pages.

To fix this, in sptlrpc_enc_pool_get_pages(), do not make ptlrpcd
threads wait in queue if encoding pool has already reached its maximum
capacity. Instead, return -ENOMEM. If functions calling ptl_send_rpc()
get -ENOMEM, then put back request in queue by moving it back to
RQ_PHASE_NEW phase.

As an optimization, do not call ptl_send_rpc() again for requests that
already failed to allocate in the enc_pool, as long as there is not
enough memory in the enc_pool to satisfy theirs needs.

In /sys/fs/lustre/sptlrpc/encrypt_page_pools, add a new 'out of mem'
stat to track how many requests fail to allocate memory in the
enc_pool.

When trying to replace a dead sec context with a new one, we must
ensure the new context is already up-to-date.
If it is not the case, just return from sptlrpc_req_replace_dead_ctx()
and come later when the new context has been updated.

The minimum record size will be recorded in llh_size, which is
only used by fixed size record llog now, and also add another
flag LLOG_F_IS_FIXSIZE to indicate the fix size record llog.

Subject: iio:cros_ec_sensors: Swap from a select to a depends in Kconfig

Would have merged this into the original patch as a fixup but I've already
pushed that out as an immutable branch for others to use so it'll have
to be a separate patch.  The original select had a typo as well.

Trying to do this via a select was opening a can of worms due to
a tree of other elements that would also have needed selecting.
A simple depends seems much mroe straight forward and appropriate in this
case.

Subject: iio: si7020: Add devicetree support and trivial bindings

This adds devicetree support for the si7020 iio driver. Since it works
well without requiring any additional property, its compatible string is
added to the trivial i2c devices bindings list.

IIO devices have a /sys/bus/iio/devices/iio:deviceX/power/ directory
that allows viewing and controling various power parameters. The tsl2583
driver also has an additional custom sysfs attribute named power_state
that is not needed. This patch removes the redundant power_state sysfs
attribute.

Subject: staging: iio: tsl2583: check return values from taos_chip_{on,off}

The return value from taos_chip_on() and taos_chip_off() was not
checked in taos_luxtable_store() and taos_probe(). This patch adds
proper error checking to these function calls.

Subject: staging: iio: tsl2583: convert to use iio_chan_spec and
 {read,write}_raw

The tsl2583 driver directly creates sysfs attributes that should instead
be created by the IIO core on behalf of the driver. This patch adds the
iio_chan_spec array, the relevant info_mask elements and the read_raw()
and write_raw() functions to take advantage of features provided by the
IIO core. These sysfs attributes were migrated with this patch:
illuminance0_input, illuminance0_calibbias,
illuminance0_integration_time. This also exposes the raw values read
from the two channels on the sensor.

With this change, these four sysfs entries have their prefix changed
from illuminance0_ to in_illuminance_. This is deemed to be acceptable
since none of the IIO light drivers in mainline use the illuminance0_
prefix, however 8 of the IIO light drivers in mainline use the
in_illuminance_ prefix.

Also fix the units of integration_time to meet with the ABI.

Subject: staging: iio: tsl2583: convert illuminance0_calibscale sysfs attr to
 use iio_chan_spec

The illuminance0_calibscale sysfs attribute is not currently created by
the IIO core. This patch adds the appropriate mask to iio_chan_spec,
along with the appropriate data handling in the read_raw() and
write_raw() functions, so that the sysfs attribute is created by the IIO
core. With this change, this sysfs entry will have its prefix changed
from illuminance0_ to in_illuminance_.

Subject: staging: iio: tsl2583: use IIO_*_ATTR* macros to create sysfs entries

Use the IIO_CONST_ATTR, IIO_DEVICE_ATTR_RW, and IIO_DEVICE_ATTR_WO
macros for creating the in_illuminance_calibscale_available,
in_illuminance_integration_time_available, in_illuminance_input_target,
in_illuminance_calibrate, and in_illuminance_lux_table sysfs entries.
Previously these sysfs entries were prefixed with illuminance0_, however
they are now prefixed with in_illuminance_ to make these sysfs entries
consistent with how the IIO core is creating the other sysfs entries.

Subject: staging: iio: tsl2583: add error code to sysfs store functions

in_illuminance_input_target_store() and in_illuminance_calibrate_store()
validated the data from userspace, however it would not return an
error code to userspace if an invalid value was passed in. This patch
changes these functions so that they return -EINVAL if invalid data is
passed in.

in_illuminance_input_target_show(), in_illuminance_input_target_store(),
in_illuminance_calibrate_store(), and in_illuminance_lux_table_store()
accesses data from the tsl2583_chip struct. Some of these fields can be
modified by other parts of the driver concurrently. This patch adds the
mutex locking to these sysfs attributes.

Subject: staging: iio: set proper supply name to devm_regulator_get()

The name passed to devm_regulator_get() should match the name of the
supply as specified in the device datasheet. This makes it clear what
power supply is being referred to in case of presence of other
regulators.

Currently, the supply name specified on the affected devices is 'vcc'.
Use lowercase version of the datasheet name to specify the supply
voltage.

Subject: staging: iio: rework regulator handling

Currently, the affected drivers ignore all errors from regulator_get().
The way it is now, it also breaks probe deferral (EPROBE_DEFER). The
correct behavior is to propagate the error to the upper layers so they
can handle it accordingly.

Rework the regulator handling so that it matches the standard behavior.
If the specific design uses a static always-on regulator and does not
explicitly specify it, regulator_get() will return the dummy regulator.

The following semantic patch was used to apply the change:
@r1@
expression reg, dev, en, volt;
@@

reg = \(devm_regulator_get\|regulator_get\)(dev, ...);
if (
- !
   IS_ERR(reg))
+	return PTR_ERR(reg);
(
- {	en = regulator_enable(reg);
-	if (en) return en; }
+
+	en = regulator_enable(reg);
+	if (en) {
+		dev_err(dev, "Failed to enable specified supply\n");
+		return en; }
|
+
- {	en = regulator_enable(reg);
-	if (en)	return en;
-	volt = regulator_get_voltage(reg); }
+	en = regulator_enable(reg);
+	if (en) {
+		dev_err(dev, "Failed to enable specified supply\n");
+		return en;
+	}
+	volt = regulator_get_voltage(reg);
)

@r2@
expression arg;
@@

-	if (!IS_ERR(arg)) regulator_disable(arg);
+	regulator_disable(arg);

Hand-edit the debugging prints with the supply name to become more
specific.

Subject: staging: iio: ad9832: clean-up regulator 'reg'

Rename regulator 'reg' to 'avdd' so as to be clear what regulator it
stands for specifically. Additionally, get rid of local variable 'reg'
and use direct assignment instead. Update also the goto label pertaining
to the avdd regulator during disable.

 data legitimacy

Neither sample frequency value nor hysteresis value can be set to be a
negative number, check and return "Invalid argument" if they are negative.

If not do this change, sample_frequency will be set into some unknown
value, read hysteresis value after write negative number will return
"Invalid argument".

Subject: staging: iio: tsl2583: i2c_smbus_write_byte() / i2c_smbus_read_byte()
 migration

There were several places where the driver would first call
i2c_smbus_write_byte() to select the register on the device, and then
call i2c_smbus_read_byte() to get the contents of that register. The
code would look roughly like:

/* Select register */
i2c_smbus_write_byte(client, REGISTER);

/* Read the the last register that was written to */
int data = i2c_smbus_read_byte(client);

Rewrite this to use i2c_smbus_read_byte_data() to combine the two
calls into one:

int data = i2c_smbus_read_byte_data(chip->client, REGISTER);

Verified that the driver still functions correctly using a TSL2581
hooked up to a Raspberry Pi 2.

This fixes the following warnings that were found by the
kbuild test robot that were introduced by commit 8ba355cce3c6 ("staging:
iio: tsl2583: check for error code from i2c_smbus_read_byte()").

drivers/staging/iio/light/tsl2583.c:365:5-12: WARNING: Unsigned
expression compared with zero: reg_val < 0

drivers/staging/iio/light/tsl2583.c:388:5-12: WARNING: Unsigned
expression compared with zero: reg_val < 0

This also removes the need for the taos_i2c_read() function since all
callers were only calling the function with a length of 1.

taos_probe() queries the all of the sensor's registers and loads all of
the values into a buffer stored on the stack. Only the chip ID register
was actually used. Change the probe function to just query the chip ID
register on the device.

Verified that the driver still functions correctly using a TSL2581

Subject: staging: iio: tsl2583: remove redundant power off sequence in
 taos_chip_on()

taos_chip_on() explicitly turns the sensor power on and then writes the
8 registers that are stored in taos_config. The first register in
taos_config is the CONTROL register and the configuration is set to
turn the power off. The existing state sequence in taos_chip_on() is:

- Turn device power on
- Turn device power off (via taos_config)
- Configure other 7 registers (via taos_config)
- Turn device power on, enable ADC

This patch changes the code so that the device is not powered off via
taos_config.

Verified that the driver still functions correctly using a TSL2581
hooked up to a Raspberry Pi 2.

 table

in_illuminance_lux_table_store() shuts down the chip, updates the
contents of the lux table, and then turns the chip back on. The values
in lux table are not used by the chip and are only used internally by
the driver. It is not necessary to change the power state on the chip.
This patch removes the calls to taos_chip_off() and taos_chip_on()
in in_illuminance_lux_table_store().

Subject: staging: iio: tsl2583: remove redudant i2c call in
 taos_als_calibrate()

taos_als_calibrate() queries the control register to determine if the
unit is powered on and has the ADC enabled. It then queries the same
register a second time to determine if the ADC reading is valid. This
patch removes the redundant i2c_smbus_read_byte_data() call.

Verified that the driver still functions correctly using a TSL2581
hooked up to a Raspberry Pi 2.

Subject: staging: unisys: visorbus: move DEVICE_ATTR_RO defs as-per
 conventions

The kernel convention is for DEVICE_ATTR_RO(<attr>) definitions to occur
immediately after the functions that implement the attribute behaviors.
DEVICE_ATTR_RO definitions in visorbus_main.c have been moved to comply
with this convention.

Subject: staging: unisys: visorbus: convert client_bus_info sysfs to debugfs

Previously, the sysfs entry (assuming traditional sysfs mountpoint):

    /sys/bus/visorbus/devices/visorbus<n>/client_bus_info

violated kernel conventions by printing more than one item.  This along
with the fact that the data emitted was diagnostic data (intended to
shadow the client driver info provided via s-Par livedumps) made it a
logical candidate for debugfs.  So this patch moves this sysfs entry to
debugfs as (assuming traditional debugfs mountpoint):

    /sys/kernel/debug/visorbus/visorbus<n>/client_bus_info

Data for this debugfs is emitted using the preferred seq_file interface,
which allowed a vastly-simplified version of vbuschannel_print_devinfo()
to format the individual output components.

Functionality was verified as follows:

  [root@sparguest visorbus]# mount | grep debug
  debugfs on /sys/kernel/debug type debugfs (rw)
  [root@sparguest visorbus]# pwd
  /sys/kernel/debug/visorbus

Removed intializations from visorchipset_open(), visorchipset_init()
and moved the memset in initialize_controlvm_payload_info() down in
case of early returns from the function.

Subject: staging: unisys: visorbus: fix double response

This patch addresses the problem that we were sending double responses
back to the s-Par Firmware when processing CONTROLVM Messages. Every
message responds individually and the epilog functions would send a
response as well.

Since a message could delay the response, it was decided to remove the
extra response from the epilog function.

Subject: staging: unisys: visorbus: in my_device_destroy don't call
 device_epilog

The function my_device_destroy should call chipset_device_destroy
directly instead of calling device_epilog. Since this was the last
function to use device_epilog that function was removed as well.

This commit adds a default condition to those case statements that do not
already have one. This is done to provide both a logical covering of all
conditions, as well as to maintain uniformity with the rest of the Unisys
driver set.

Subject: staging: vc04_services: call sg_init_table to init scatterlist

Call the sg_init_table function to correctly initialze
the DMA scatterlist.  This function is required to completely
initialize the list and is mandatory if DMA debugging is
enabled in the build configuration.

One of the purposes of sg_init_table is to set
the magic "cookie" on each list element and ensure
the chain end is marked.

Subject: staging: vc04_services: remove vchiq_copy_from_user

The vchiq_copy_from_user function is not portable
and is consider "bad practice."  Replace this function
with a callback based mechanism that is passed downward
on the stack.  When it is actually time to copy the data,
the callback is called to copy the data into the message.

This callback is provided internally for userland calls
through ioctls on the device.

NOTE: Internal clients will need to be modified to work
with the new internal API.

Test Run:
vchiq_test -p 1
vchiq_test -f 10

Both tests pass.

Internal API Changes:

Change vchi_msg_queue to:
int32_t
vchi_msg_queue(VCHI_SERVICE_HANDLE_T handle,
	       ssize_t (*copy_callback)(void *context, void *dest,
				        size_t offset, size_t maxsize),
	       void *context,
	       uint32_t data_size );

Remove:
vchi_msg_queuev_ex
vchi_msg_queuev

These functions were not implemented anyway so no need to fix them. It's
easier to just remove them.

Subject: staging: vc04_services: parse_rx_slots() - Fix compiler warning

vc04_services contains a debug logging mechanism.  The log is
maintained in a shared memory area between the kernel and the
firmware.  Changing the sizes of the data in this area would
require a firmware change which is distributed independently
from the kernel binary.

One of the items logged is the address of received messages.
This address is a pointer, but the debugging slot used to store
the information is a 32 bit integer.

Luckily, this value is never interpreted by anything other
then debug tools and it is expected that a human debugging
the kernel interpret it.

This change adds a cast to long before the original cast
to int to silence the warning.

Subject: staging: vchiq_core: fix service dereference in unlock_service

The service state is dereferenced before BUG_ON and outside of the
spin lock. So in order to avoid possible NULL pointer dereferences or
races move the whole scope at a safer place.

This issue has been found by Cppcheck.

Subject: staging: vchiq_arm: remove hardcoded buffer length

We better use sizeof instead of hardcoding buffer length multiple
times. This make it easier to increase the buffer in the future.
In order to keep below 80 chars limit make the variable name shorter.

The current order during module probe is prone to race conditions:

* debugfs entries, sysfs entries, platform code

So fix this by swapping the steps debugfs entries and platform code.
As a benefit this saves us a clean up step in the error path.

There are few functions where we need to free previously allocated

_init_cmd_priv() and _r8712_init_xmit_priv(), in few places we are
not freeing previously allocated memory when kmalloc fails.

This patch compresses two lines into a single line
if immediate return statement is found. Remove variable data as
it is no longer needed.

It is done using script Coccinelle. And coccinelle uses the following
semantic patch for this compression function

Subject: staging/lustre: conflicting PW & PR extent locks on a client

PW lock isn't replayed once a lock is marked
LDLM_FL_CANCELING and glimpse lock doesn't wait for
conflicting locks on the client. So the server will
grant a PR lock in response to the glimpse lock request,
which conflicts with the PW lock in LDLM_FL_CANCELING
state on the client.

Lock in LDLM_FL_CANCELING state may still have pending IO,
so it should be replayed until LDLM_FL_BL_DONE is set to
avoid granted conflicting lock by a server.

Subject: staging/lustre/llite: clear inode timestamps after losing UPDATE lock

Otherwise, those leftovers would interfere with new timestamps
especially when the timestamps are set back in time on the other
clients.

Subject: staging/lustre: Get rid of cl_env hash table

cl_env hash table is under heavy contention when there are lots of
processes doing IO at the same time;
reduce lock contention by replacing cl_env cache with percpu array;
remove cl_env_nested_get() and cl_env_nested_put();
remove cl_env_reenter() and cl_env_reexit();

Subject: staging/lustre/llite: drop_caches hangs in cl_inode_fini()

This patch releases cl_pages on error in ll_write_begin()
to avoid memory and object reference leaks. Also, it
reuses per-cpu lu_env in ll_invalidatepage() in the same
way as done in ll_releasepage().

If there is no request passed into ldlm_cli_enqueue, the enqueue

this kind of request is mainly related to EXTENT locks enqueue
requests (except for glimpse EXTENT lock for it has an intent).

Subject: staging/lustre/ptlrpc: Suppress error for flock requests

-EAGAIN is a normal return when requesting POSIX flocks.
We can't recognize exactly that case here, but it's the
only case that should result in -EAGAIN on LDLM_ENQUEUE, so
don't print to console in that case.

Subject: staging/lustre/ptlrpc: Correctly calculate hrp->hrp_nthrs

cpu_pattern can specify exactly 1 cpu in a partition:
"0[0]". That means CPT0 will have CPU 0. CPU 0 can have
hyperthreading enabled. This combination would result in

weight = cfs_cpu_ht_nsiblings(0);
hrp->hrp_nthrs = cfs_cpt_weight(ptlrpc_hr.hr_cpt_table, i);
hrp->hrp_nthrs /= weight;

evaluating to 0. Where
cfs_cpt_weight(ptlrpc_hr.hr_cpt_table, i) == 1
weight == 2

Therefore, if hrp_nthrs becomes zero, just set it to 1.

Subject: staging/lustre/llite: update ras window correctly

When stride-RA hit case miss, we only reset normal sequential
read-ahead window, but not reset the stride IO to avoid the overhead
of re-detecting stride IO. While when the normal RA window is set
to not insect with the stride-RA window, when we try to increase
the stride-RA window length later, the presumption does not hold.

This patch resets the stride IO as well in this case.

Subject: staging/lustre/llite: do not clear uptodate bit in page delete

Otherwise, if the race between page fault and truncate occurs, it
will cause the page fault routine to return an EIO error.

In filemap_fault() {
    page_not_uptodate:
    ...
        ClearPageError(page);
        error = mapping->a_ops->readpage(file, page);
        if (!error) {
                wait_on_page_locked(page);
                if (!PageUptodate(page))
                        error = -EIO;
    }
    ...
}

However, I tend to think this is a defect in kernel implementation,
because it assumes PageUptodate shouldn't be cleared but file read
routine doesn't make the same assumption.

Subject: staging: iio: tsl2583: fix unused function warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removing a call to the taos_chip_off() makes it unused when CONFIG_PM
is disabled:

drivers/staging/iio/light/tsl2583.c:438:12: error: ‘taos_chip_off’ defined but not used [-Werror=unused-function]

This removes all the #ifdef in this file, and marks the PM functions as
__maybe_unused instead, which is more reliable and gives us better
compile time coverage.

 hfa384x_usbin_callback

This patch avoids using BUG_ON() from driver,
and return from hfa384x_usbin_callback with WARN_ON()
if skb was NULL or data in skb is different from expected one.

Subject: staging: sm750fb: prefix global identifiers

Renaming some symbols inside this driver caused a conflict with
an existing function, which in turn results in a link error:

drivers/staging/sm750fb/sm750fb.o: In function `enable_dma':
ddk750_hwi2c.c:(.text.enable_dma+0x0): multiple definition of `enable_dma'

This adds a sm750_ prefix to each global symbol in the sm750fb
driver that does not already have one. I manually looked for the
symbols and then converted the driver using

for i in calc_pll_value format_pll_reg set_power_mode set_current_gate    \
	enable_2d_engine enable_dma enable_gpio enable_i2c hw_set2dformat \
	hw_de_init hw_fillrect hw_copyarea hw_imageblit hw_cursor_enable  \
	hw_cursor_disable hw_cursor_setSize hw_cursor_setPos		  \
	hw_cursor_setColor hw_cursor_setData hw_cursor_setData2 ;
do
		sed -i "s:\<$i\>:sm750_$i:" drivers/staging/sm750fb/*.[ch]
done

Subject: staging: greybus: uart: fix invalid user-pointer check

Drop invalid user-pointer check from TIOCGSERIAL handler.

A NULL-pointer can be valid in user space and copy_to_user() takes care
of sanity checking.

Subject: staging: vc04_services: add vchiq_pagelist_info structure

The current dma_map_sg based implementation for bulk messages
computes many offsets into a single allocation multiple times in
both the create and free code paths.  This is inefficient,
error prone and in fact still has a few lingering issues
with arm64.

This change replaces a small portion of that inplementation with
new code that uses a new struct vchiq_pagelist_info to store the
needed information rather then complex offset calculations.

This improved implementation should be more efficient and easier
to understand and maintain.

Tests Run(Both Pass):
vchiq_test -p 1
vchiq_test -f 10

It would be nice to be able to build this code on other platforms other

turn off BROKEN as the code can now build properly thanks to Michael's
work.

Subject: iio: cros_ec_sensors_core: fix unsigned compared less than zero on
 status

status is a u8 hence the check if status is less than zero has no effect.
Fix this by replacing status with int ret so the less than zero compare
will correctly detect errors.

Issue found with static analysis with CoverityScan, CID 1375919

Subject: iio: imu: inv_mpu6050: inform the i2c mux core about how it is used

The i2c mux core can then take appropriate action depending on if it is
used for an actual i2c mux, or for an arbitrator or gate. In this case
it is used as a gate.

This will make devicetree bindings simpler when they are eventually
added.

Subject: iio: gyro: st_gyro: inline per-sensor data

We have #defines for all the individual sensor registers and
value/mask pairs #defined at the top of the file and used at
exactly one spot.

This is usually good if the #defines give a meaning to the
opaque magic numbers.

However in this case, the semantic meaning is inherent in the
name of the C99-addressable fields, and that means duplication
of information, and only makes the code hard to maintain since
you every time have to add a new #define AND update the site
where it is to be used.

Get rid of the #defines and just open code the values into the
appropriate struct elements. Make sure to explicitly address
the .hz and .value fields in the st_sensor_odr_avl struct
so that the meaning of all values is clear.

This patch is purely syntactic should have no semantic effect.

From 57d035545165a354a52f5d16d46efbb318a2fff4 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>

Subject: iio: magn: st_magn: inline per-sensor data

We have #defines for all the individual sensor registers and
value/mask pairs #defined at the top of the file and used at
exactly one spot.

This is usually good if the #defines give a meaning to the
opaque magic numbers.

However in this case, the semantic meaning is inherent in the
name of the C99-addressable fields, and that means duplication
of information, and only makes the code hard to maintain since
you every time have to add a new #define AND update the site
where it is to be used.

Get rid of the #defines and just open code the values into the
appropriate struct elements. Make sure to explicitly address
the .hz and .value fields in the st_sensor_odr_avl struct
so that the meaning of all values is clear.

This patch is purely syntactic should have no semantic effect.

From 91a86a3b89462a7b0af8553428a6101df33633ac Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Wed, 9 Nov 2016 16:10:00 +0100
Subject: iio: pressure: st_pressure: inline per-sensor data

We have #defines for all the individual sensor registers and
value/mask pairs #defined at the top of the file and used at
exactly one spot.

This is usually good if the #defines give a meaning to the
opaque magic numbers.

However in this case, the semantic meaning is inherent in the
name of the C99-addressable fields, and that means duplication
of information, and only makes the code hard to maintain since
you every time have to add a new #define AND update the site
where it is to be used.

Get rid of the #defines and just open code the values into the
appropriate struct elements. Make sure to explicitly address
the .hz and .value fields in the st_sensor_odr_avl struct
so that the meaning of all values is clear.

This patch is purely syntactic should have no semantic effect.

Subject: staging: iio: tsl2583: split out functionality of taos_chip_on()

taos_chip_on() reads an eight member array called taos_config
that contains the desired state of the chip's registers. Only four
of the registers actually need to be written to. The four that do
not need to be written to are for the {low,high} byte of the lower
interrupt threshold and the {low,high} byte of the upper interrupt
threshold. Interrupts are currently not supported by this driver
so there is no need to write to these registers.

This patch removes the taos_config array and separates out the
i2c calls that write to the CONTROL, TIMING, INTERRUPT and ANALOG
registers. This is part of a larger refactor that was split up to
make the code review easier.

Subject: staging: iio: tsl2583: fix issue with changes to calibscale and
 int_time not being set on the chip

When updating the in_illuminance_calibscale and
in_illuminance_integration_time sysfs attributes, these values were not
actually written to the chip. The chip would continue to use the old
parameters. Extracted out tsl2583_set_als_gain() and
tsl2583_set_als_time() functions that are now called when these sysfs
attributes are updated. The chip initialization also calls these these
new functions.

Subject: iio:core: add a callback to allow drivers to provide _available
 attributes

A large number of attributes can only take a limited range of values.
Currently in IIO this is handled by directly registering additional
*_available attributes thus providing this information to userspace.

It is desirable to provide this information via the core for much the same
reason this was done for the actual channel information attributes in the
first place.  If it isn't there, then it can only really be accessed from
userspace.  Other in kernel IIO consumers have no access to what valid
parameters are.

Two forms are currently supported:
* list of values in one particular IIO_VAL_* format.
	e.g. 1.300000 1.500000 1.730000
* range specification with a step size:
	e.g. [1.000000 0.500000 2.500000]
	equivalent to 1.000000 1.5000000 2.000000 2.500000

An addition set of masks are used to allow different sharing rules for the
*_available attributes generated.

This allows for example:

in_accel_x_offset
in_accel_y_offset
in_accel_offset_available.

We could have gone with having a specification for each and every
info_mask element but that would have meant changing the existing userspace
ABI.  This approach does not.

From: Peter Rosin <peda@axentia.se>
Date: Tue, 8 Nov 2016 12:58:52 +0100
Subject: iio: inkern: add helpers to query available values from channels

Specifically a helper for reading the available maximum raw value of a
channel and a helper for forwarding read_avail requests for raw values
from one iio driver to an iio channel that is consumed.

These rather specific helpers are in turn built with generic helpers
making it easy to build more helpers for available values as needed.

Subject: iio: envelope-detector: ADC driver based on a DAC and a comparator

The DAC is used to find the peak level of an alternating voltage input
signal by a binary search using the output of a comparator wired to
an interrupt pin. Like so:

+		            |       |
+		            '-------'
+		The boolean invert attribute (0/1) should be set when the
+		input signal is centered around the maximum value of the
+		dac instead of zero. The envelope detector will search
+		from below in this case and will also invert the result.
+		The edge/level of the interrupt is also switched to its
+		opposite value.

+Description:
+		Number of milliseconds to wait for the comparator in each
+		step of the binary search for the input peak level. Needs

Subject: staging: iio: tsl2583: check if chip is in a working state in
 in_illuminance_calibrate_store

in_illuminance_calibrate_store() did not check to see if the chip is
in a working state. This patch adds the proper check. The return value
from taos_als_calibrate() was also not checked in this function, so the
proper check was also added while changes are being made here.

taos_get_lux checks to see if the chip is in a working state. This
check is not necessary since it is only called from tsl2583_read_raw
and in_illuminance_calibrate_store (via taos_als_calibrate). The chip
state is already checked by these functions.

Subject: staging: iio: tsl2583: remove unnecessary chip status checks in
 suspend/resume

The device probing and the suspend/resume code checks a flag internal to
the driver that determines whether or not the chip is in a working
state. These checks are not needed. This patch removes the unnecessary
checks. It will do no harm to the hardware if the chip is
reinitialized if it is already powered on.

Subject: staging: iio: tsl2583: remove redundant write to the control register
 in taos_probe()

taos_probe() calls i2c_smbus_write_byte() to select the control
register, however there are no subsequent calls to
i2c_smbus_read_byte(). The write call is unnecessary and is removed by
this patch.

Verified that the driver still functions correctly using a TSL2581
hooked up to a Raspberry Pi 2.

There are several places in the code where the function name is

the log message. This also clarifies some of the error messages to match
the code and ensures that the correct priority is used since the message
is already being changed.

From 686c592284d3ba3ed4e63921e60da0d62c754c85 Mon Sep 17 00:00:00 2001
From: Brian Masney <masneyb@onstation.org>
Date: Sat, 12 Nov 2016 13:19:23 -0500
Subject: staging: iio: tsl2583: unify function and variable prefix to tsl2583_

Some functions and variables were prefixed with either taos, tsl258x,
taos2583, or tsl2583. Change everything to use the tsl2583 prefix since
that is the name of the .c file. The taos_settings member inside the
taos_settings struct was renamed to als_settings.

Subject: staging: iio: tsl2583: fix alignment of #define values

Most of the values in the #defines have their values aligned on a single
column, but some do not. This changes the remaining defines to use
consistent alignment with the majority to improve code readability.

If channel 0 does not have any data, then the code sets the lux to zero.
The corresponding comment says that the last value is returned. This
updates the comment to correctly reflect what the code does. It also
clarifies the comment about why 0 is returned.

Subject: staging: iio: tsl2583: change tsl2583_als_calibrate() to return 0 on
 success

tsl2583_als_calibrate() returns the newly computed gain_trim if the
calibration was successful. This function is only called by
in_illuminance_calibrate_store() and the return value inside that
sysfs attribute is only checked to see if an error was returned.
This patch changes tsl2583_als_calibrate() to return 0 on success.

Subject: staging: iio: tsl2583: move from a global to a per device lux table

The driver contains a global lux table that can be updated via sysfs.
Change this to a per device lux table so that multiple devices can be
hooked up to the same system with different lux tables.

There are 10 entries, plus 1 for the termination segment, set aside for
the entries in the lux table. When updating the lux table via sysfs,
only 9 entries, plus the terminator, could be added. This changes
the code to allow for the 10 entries, plus the terminator.

The header only listed the tsl2580 and tsl2581 devices as supported by
this driver. This patch adds the tsl2583 since it is also supported by
this driver.

Subject: staging: iio: tsl2583: remove unnecessary memset call

The entries in the lux table (als_device_lux) can be updated via sysfs
through the function in_illuminance_lux_table_store(). The last row in
the table must be terminated with values that are zero. The sysfs code
already ensures that the last row is all zeros. The call to memset to
clear out the table is not needed so this patch removes the unnecessary
call.

drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:193:39-40: WARNING: Use ARRAY_SIZE

 Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element

Semantic patch information:
 This makes an effort to find cases where ARRAY_SIZE can be used such as
 where there is a division of sizeof the array by the sizeof its first
 element or by any indexed element or the element type. It replaces the
 division of the two sizeofs by ARRAY_SIZE.

Subject: staging: lustre: lov: init LOV stripe type beforehand

When lu_object_alloc() reaches to LOV object init, we need initialize
its stripe type beforehand, so that if something wrong in the conf
buffer, the object chain need to be traversed to free what has been
allocated, with LOV object type be set as LLT_EMPTY, and when the LOV
part is reached, it won't panic without knowing what stripe type it
is.

This patch also improves debug messages in lsm_unpackmd_common(), and
does not return error if the LOV device is still processing config
log while trying to verify a layout buffer.

James Simmons reports:

This broke when I converted the 32-bit get_seconds() into
ktime_get_{real_,}seconds() inconsistently. Either
one of those two would have worked, but mixing them
does not.

Staying with the original intention of the patch, this
changes the ktime_get_seconds() calls into ktime_get_real_seconds(),
using real time instead of mononic time.

Subject: staging: lustre: osc: Do not merge extents with partial pages

After range lock is introduced to Lustre, it's possible for
multiple threads to submit osc_extents with partial pages, and
finally I/O engine may try to merge these extents, which will
end up with assert in osc_build_rpc().

In this patch, osc_extent::oe_no_merge is introduced, and this flag
is set if osc_extent submitted via osc_io_submit() includes partial
pages. This flag is used by I/O engine to stop merging this kind
of extents.

Subject: staging: lustre: hsm: prevent migration of HSM archived files

The reference copytool cannot handle migration of HSM archive
files. In the MDT migration path check for HSM attributes and fail if
they are present. In the LMV layer allow creation of volatile files
with any MDT index. Add a test to sanity-hsm to ensure that attempting
to migrate an HSM archive file is handled safely.

Subject: staging: lustre: mdc: remove console spew from mdc_ioc_fid2path

In some cases with a very long pathname, such as with sanity.sh
test_154c, mdc_ioc_fid2path() would spew long debug messages to
the log, because libcfs_debug_vmsg2() refuses to log messages over
one page in size.

Truncate the debug message to only log the last 512 characters
of the pathname, which is sufficient for most debugging, saves a
bit of space in the debug log, and will prevent the debug logging
from printing to the console in the first place.

Subject: staging: lustre: ptlrpc: race at req processing

Fix: 5c689e689baa ("staging/lustre/ptlrpc: race at req processing")
decreased the race window, but does not remove it. Disable rq_resend
right after MSG_REPLAY flag set. Import lock protects two threads
from race between set/clear MSG_REPLAY and rq_resend flags.

Subject: staging: lustre: llite: lookup master inode by ilookup5_nowait

Do not lookup master inode by ilookup5, instead it should
use ilookup5_nowait, otherwise it will cause dead lock,

1. Client1 send chmod req to the MDT0, then on MDT0, it
   enqueues master and all of its slaves lock, (mdt_attr_set()
   ->mdt_lock_slaves()), after gets master and stripe0 lock,
   it will send the enqueue request(for stripe1) to MDT1, then
   MDT1 finds the lock has been granted to client2. Then MDT1
   sends blocking ast to client2.

2. At the same time, client2 tries to unlink the striped
   dir (rm -rf striped_dir), and during lookup, it will hold
   the master inode of the striped directory, whose inode state
   is NEW, then tries to revalidate all of its slaves,
   (ll_prep_inode()->ll_iget()->ll_read_inode2()->
   ll_update_inode().). And it will be blocked on the server
   side because of 1.

3. Then the client get the blocking_ast request, cancel the
   lock, but being blocked by ilookup5 in ll_md_blocking_ast(),
   because the inode state is still NEW.

From f6763b6898688b5c24a5a6301da6ce6a76eecfb0 Mon Sep 17 00:00:00 2001
From: Henri Doreau <henri.doreau@cea.fr>

Subject: staging: lustre: obd: Remove dead code in precleanup

There used to be several pre-cleanup phases, but
only OBD_CLEANUP_EXPORTS is actually used.  Thus
remove the whole notion of precleanup phases.

Subject: staging: lustre: obdclass: remove structure holes to reduce memory

Fix the alignment of fields in commonly-used structures to reduce
memory usage on the client and server.  Structures fixed:

ptlrpc_reply_state: reduced by 8 bytes
obd_device:         reduced by 16 bytes
niobuf_local:       reduced by 8 bytes

Subject: staging: lustre: lmv: revalidate the dentry for striped dir

If there are bad stripe during striped dir revalidation,
most likely due the race between close(unlink) and
getattr, then let's revalidate the dentry, instead of
return error, like normal directory.

Subject: staging: lustre: llite: tar restore fails for HSM released files.

If you create a file, archive and release it, it keeps only a
link and all information in xattr. If you tar the file
with --xattr you will store the same striping information and link
information in the tar. If you delete the file, the file and archive
state does not make sense. Now if you restore the file using tar
with xattr having the RELEASED flag turned on, then it is not correct
because this is a new file. Hence ignoring the HSM xattr and masking
out the "RELEASED" flag for the files, which are not archived.

-/** \struct cl_req
- * Transfer.
- *
- * There are two possible modes of transfer initiation on the client:
- *
- *     - immediate transfer: this is started when a high level io wants a page
- *       or a collection of pages to be transferred right away. Examples:
- *       read-ahead, synchronous read in the case of non-page aligned write,
- *       page write-out as a part of extent lock cancellation, page write-out
- *       as a part of memory cleansing. Immediate transfer can be both
- *       cl_req_type::CRT_READ and cl_req_type::CRT_WRITE;
- *
- *     - opportunistic transfer (cl_req_type::CRT_WRITE only), that happens
- *       when io wants to transfer a page to the server some time later, when
- *       it can be done efficiently. Example: pages dirtied by the write(2)
- *       path.
- *
- * In any case, transfer takes place in the form of a cl_req, which is a
- * representation for a network RPC.
- *
- * Pages queued for an opportunistic transfer are cached until it is decided
- * that efficient RPC can be composed of them. This decision is made by "a
- * req-formation engine", currently implemented as a part of osc
- * layer. Req-formation depends on many factors: the size of the resulting
- * RPC, whether or not multi-object RPCs are supported by the server,
- * max-rpc-in-flight limitations, size of the dirty cache, etc.
- *
- * For the immediate transfer io submits a cl_page_list, that req-formation
- * engine slices into cl_req's, possibly adding cached pages to some of
- * the resulting req's.
- *
- * Whenever a page from cl_page_list is added to a newly constructed req, its
- * cl_page_operations::cpo_prep() layer methods are called. At that moment,
- * page state is atomically changed from cl_page_state::CPS_OWNED to
- * cl_page_state::CPS_PAGEOUT or cl_page_state::CPS_PAGEIN, cl_page::cp_owner
- * is zeroed, and cl_page::cp_req is set to the
- * req. cl_page_operations::cpo_prep() method at the particular layer might
- * return -EALREADY to indicate that it does not need to submit this page
- * at all. This is possible, for example, if page, submitted for read,
- * became up-to-date in the meantime; and for write, the page don't have
- * dirty bit marked. \see cl_io_submit_rw()
- *
- * Whenever a cached page is added to a newly constructed req, its
- * cl_page_operations::cpo_make_ready() layer methods are called. At that
- * moment, page state is atomically changed from cl_page_state::CPS_CACHED to
- * cl_page_state::CPS_PAGEOUT, and cl_page::cp_req is set to
- * req. cl_page_operations::cpo_make_ready() method at the particular layer
- * might return -EAGAIN to indicate that this page is not eligible for the
- * transfer right now.
- *
- * FUTURE
- *
- * Plan is to divide transfers into "priority bands" (indicated when
- * submitting cl_page_list, and queuing a page for the opportunistic transfer)
- * and allow glueing of cached pages to immediate transfers only within single
- * band. This would make high priority transfers (like lock cancellation or
- * memory pressure induced write-out) really high priority.

Subject: staging: lustre: obd: rename obd_unpackmd() to md_unpackmd()

obd_unpackmd() is only implemented by LMV so move it from OBD
operations to OBD MD operations and update the prototype to reflex
the actual usage. Remove the unused function obd_free_memmd().

Subject: staging: lustre: ptlrpc: mbits is sent within ptlrpc_body

ptlrpc is using rq_xid as matchbits of bulk data, which means it
has to change rq_xid for bulk resend to avoid several bulk data
landing into the same buffer from different resends.

This patch uses one of reserved __u64 of ptlrpc_body to transfer
mbits to peer, matchbits is now separated from xid. With this change,
ptlrpc can keep rq_xid unchanged on resend, it only updates matchbits
for bulk data.

This protocol change is only applied if both sides of connection have
OBD_CONNECT_BULK_MBITS, otherwise, ptlrpc still uses old approach and
update xid while resending bulk.

Subject: staging: lustre: lmv: lock necessary part of lmv_add_target

Release lmv_init_mutex once the new target is added
into lmv_tgt_desc, so lmv_obd_connect will not be
serialized.

New target should be allowed to added to fld client
lists, so FLD can always choose new added target to
do the FLD lookup request, and also remove some noise
error messages in this process.

Subject: staging: lustre: lnet: add offset for selftest brw

In current lnet selftest, both client and server side bulk have
no offset and we can only test page aligned IO, this patch changed
this:

- user can set brw offset by lst add_test ... brw off=OFFSET ...
- offset is only effective on client side so far
- to simply implementation, offset needs to be eight bytes aligned

From 0ffaa9c8eb2faab0cb2dbbe46a83ec5f96df0310 Mon Sep 17 00:00:00 2001
From: Henri Doreau <henri.doreau@cea.fr>

Subject: staging: lustre: hsm: Use file lease to implement migration

Implement non-blocking migration based on exclusive open instead of
group lock. Implemented exclusive close operation to atomically put
a lease, swap two layouts and close a file. This allows race-free
migrations.

Make the caller responsible for retrying on failure (EBUSY, EAGAIN)
in non-blocking mode.

In blocking mode, allow applications to trigger layout swaps using a
grouplock they already own, to prevent race conditions between the
actual data copy and the layout swap. Updated lfs accordingly. File
leases are also taken in blocking mode, so that lfs migrate can issue
a warning if an application attempts to open a file that is being
migrated and gets blocked.

Timestamps (atime/mtime) are set from userland, after the layout swap
is performed, to prevent conflicts with the grouplock.

lli_trunc_sem is taken/released in the vvp_io layer, under the DLM
lock. This re-ordering fixes the original issue between truncate and
migrate.

From 7cb15d044867c83b27ed434fe7002797846002c0 Mon Sep 17 00:00:00 2001
From: Gregoire Pichon <gregoire.pichon@bull.net>
Date: Thu, 10 Nov 2016 10:51:13 -0500
Subject: staging: lustre: mdc: manage number of modify RPCs in flight

This patch is the main client part of a new feature that supports
multiple modify metadata RPCs in parallel. Its goal is to improve
metadata operations performance of a single client, while maintening
the consistency of MDT reply reconstruction and MDT recovery
mechanisms.

It allows to manage the number of modify RPCs in flight within
the client obd structure and to assign a virtual index (the tag) to
each modify RPC to help server side cleaning of reply data.

The mdc component uses this feature to send multiple modify RPCs
in parallel.

From cbafdc9816b4d59c678c08b7dbe4c1bce4a73553 Mon Sep 17 00:00:00 2001
From: Shiva Kerdel <shiva@exdev.nl>
Date: Tue, 15 Nov 2016 09:30:03 +0100
Subject: Staging: fsl-mc: include: mc: Kernel type 'int' preferred over 's16'

After following a discussion about the used integer types Dan Carpenter
pointed out that 'int' types should be used over the current change to
's16'. The reason for this is to have an upper bound instead of overflowing
the 's16' so we could still remove devices.

Subject: staging: comedi: ni_mio_common: fix M Series ni_ai_insn_read() data
 mask

For NI M Series cards, the Comedi `insn_read` handler for the AI
subdevice is broken due to ANDing the value read from the AI FIFO data
register with an incorrect mask.  The incorrect mask clears all but the
most significant bit of the sample data.  It should preserve all the
sample data bits.  Correct it.

Subject: staging: comedi: ni_mio_common: fix E series ni_ai_insn_read() data

Commit 0557344e2149 ("staging: comedi: ni_mio_common: fix local var for
32-bit read") changed the type of local variable `d` from `unsigned
short` to `unsigned int` to fix a bug introduced in
commit 9c340ac934db ("staging: comedi: ni_stc.h: add read/write
callbacks to struct ni_private") when reading AI data for NI PCI-6110
and PCI-6111 cards.  Unfortunately, other parts of the function rely on
the variable being `unsigned short` when an offset value in local
variable `signbits` is added to `d` before writing the value to the
`data` array:

			d += signbits;
		  	data[n] = d;

The `signbits` variable will be non-zero in bipolar mode, and is used to
convert the hardware's 2's complement, 16-bit numbers to Comedi's
straight binary sample format (with 0 representing the most negative
voltage).  This breaks because `d` is now 32 bits wide instead of 16
bits wide, so after the addition of `signbits`, `data[n]` ends up being
set to values above 65536 for negative voltages.  This affects all
supported "E series" cards except PCI-6143 (and PXI-6143). Fix it by
ANDing the value written to the `data[n]` with the mask 0xffff.

In `ni_ai_insn_read()`, local variable `dl` is declared as `unsigned
long`, but `unsigned int` will do.  Get rid of it and use local variable
`d` instead.  (That used to be `unsigned short`, but has been `unsigned
int` since kernel version 3.18.)

Subject: staging: wilc1000: simplify vif[i]->ndev accesses

With gcc-7, I got a new warning for this driver:

wilc1000/linux_wlan.c: In function 'wilc_netdev_cleanup':
wilc1000/linux_wlan.c:1224:15: error: 'vif[1]' may be used uninitialized in this function [-Werror=maybe-uninitialized]
wilc1000/linux_wlan.c:1224:15: error: 'vif[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized]

A closer look at the function reveals that it's more complex than
it needs to be, given that based on how the device is created
we always get

	netdev_priv(vif->ndev) == vif

Based on this assumption, I found a few other places in the same file
that can be simplified. That code appears to be a relic from times
when the assumption above was not valid.

Subject: staging: vc04_services: remove duplicate mutex_lock_interruptible

The driver tries to redefine mutex_lock_interruptible as an open-coded
mutex_lock_killable, but that definition clashes with the normal
mutex_lock_interruptible definition when CONFIG_DEBUG_LOCK_ALLOC
is set:

staging/vc04_services/interface/vchiq_arm/vchiq_killable.h:67:0: error: "mutex_lock_interruptible" redefined [-Werror]
 #define mutex_lock_interruptible mutex_lock_interruptible_killable
include/linux/mutex.h:161:0: note: this is the location of the previous definition

This simply removes the private implementation and uses the
normal mutex_lock_killable directly.

We could do the same for the down_interruptible_killable here, but
it's better to just remove the semaphores entirely from the driver,
which also takes care of that.

Subject: staging: vc04_services: clarify firmware dependency

The raspberrypi-firmware driver may be built as a loadable module,
which causes a link-time failure if the vc04_services driver is
built-in during compile-testing:

drivers/staging/vc04_services/vchiq.o: In function `vchiq_probe':
vchiq_connected.c:(.text.vchiq_probe+0x2c): undefined reference to `rpi_firmware_get'
drivers/staging/vc04_services/vchiq.o: In function `vchiq_platform_init':
vchiq_connected.c:(.text.vchiq_platform_init+0x1f0): undefined reference to `rpi_firmware_property'

This extends the dependency list to ensure the firmware is either
reachable, or completely disabled in case of compile-testing.

Subject: staging/lustre/ptlrpc: track unreplied requests

The request xid was used to make sure the ost object timestamps
being updated by the out of order setattr/punch/write requests
properly. However, this mechanism is broken by the multiple rcvd
slot feature, where we deferred the xid assignment from request
packing to request sending.

This patch moved back the xid assignment to request packing, and
the manner of finding lowest unreplied xid is changed from scan
sending & delay list to scan a unreplied requests list.

This patch also skipped packing the known replied XID in connect
and disconnect request, so that we can make sure the known replied
XID is increased only on both server & client side.

Subject: staging/lustre/ptlrpc: update imp_known_replied_xid on resend-replay

The imp_known_replied_xid should be updated when try to resend
an already replied replay request, because the xid of this replay
request could be less than current imp_known_replied_xid.

While checkpatch reported an alignment issue
its just ugly to fill in a data structure being
passed to a function. Instead fill in a lnet_md_t
on the stack and pass that to LNetMDBind.

From 715475ae4224b188ed1639db4aa291414bbf968d Mon Sep 17 00:00:00 2001
From: James Simmons <jsimmons@infradead.org>
Date: Thu, 17 Nov 2016 14:35:51 -0500

From 1add6988024030b08e4cc14001c4e64a901fa35b Mon Sep 17 00:00:00 2001
From: Fabrice Gasnier <fabrice.gasnier@st.com>

Subject: iio: adc: Add support for STM32 ADC core

Add core driver for STMicroelectronics STM32 ADC (Analog to Digital
Converter). STM32 ADC can be composed of up to 3 ADCs with shared
resources like clock prescaler, common interrupt line and analog
reference voltage.
This core driver basically manages shared resources.

From 9049531c91b4ed7948d7c8bf6e945f5da56fc501 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Mon, 14 Nov 2016 11:35:21 +0100
Subject: iio: accel: st_accel: inline per-sensor data

We have #defines for all the individual sensor registers and
value/mask pairs #defined at the top of the file and used at
exactly one spot.

This is usually good if the #defines give a meaning to the
opaque magic numbers.

However in this case, the semantic meaning is inherent in the
name of the C99-addressable fields, and that means duplication
of information, and only makes the code hard to maintain since
you every time have to add a new #define AND update the site
where it is to be used.

Get rid of the #defines and just open code the values into the
appropriate struct elements. Make sure to explicitly address
the .hz and .value fields in the st_sensor_odr_avl struct
so that the meaning of all values is clear.

This patch is purely syntactic should have no semantic effect.

Subject: staging: lustre: llog: fix wrong offset in llog_process_thread()

- llh_cat_idx may become bigger than llog bitmap size in
  llog_cat_set_first_idx() function
- it is wrong to use previous cur_offset as new buffer offset,
  new offset should be calculated from value returned by
  llog_next_block().
- optimize llog_skip_over() to find llog entry offset by index
  for llog with fixed-size records.

Subject: staging: lustre: libcfs: use uXX instead of __uXX types in headers

The types __[u|s]XX is only used for UAPI headers and userspace.
Only keep these types for the libcfs headers that are UAPI

Subject: staging/lustre: Use proper number of bytes in copy_from_user

This patch removes the usage of MAX_STRING_SIZE from
copy_from_user() and just copies enough bytes to cover
count passed in.

Subject: staging: slicoss: change some macros into inline functions

This patch changes macros into inline functions to avoid this checkpatch
check:
Macro argument 'x' may be better as '(x)' to avoid precedence issues

It also removes two macros because they aren't being used.

Subject: staging: unisys: include: fixed iochannel.h comments

The purpose of this patch is to add style consistency and beautify the
entire file.

Grammar:
Uppercased beginning of new sentences/paragraphs
Missing ' and .
Fixed several comments using prefix phrase "as is in" to "as in"
Standard Grammar

Comments:
Fixed comments to follow the multiline styling
All comments are now either same line or above variable/definitions
Removed nested slash-star comments
Removed a random comment left by accident
Aligned star comments

Subject: staging: unisys: visorbus: return EAGAIN when empty

It really isn't an error when you call visorchannel_signalremove and
there isn't anything in the queue. Just means that the IOSP didn't
process anything since the last time you checked. Just inform the
caller that it is empty by returning -EAGAIN.

Subject: iio: tsl2583: make array large enough

This array is supposed to have 10 elements.  Smatch complains that with
the current code we can have n == max_ints and read beyond the end of
the array.

Subject: iio: magnetometer: separate the values of attributes based on their
 usage type for HID compass sensor

There are 2 usage types (Magnetic Flux and Heading data field) for HID
compass sensor, thus the values of offset, scale, and sensitivity should
be separated according to their respective usage type. The changes made
are as below:
1. Hysteresis: A struct hid_sensor_common rot_attributes is created in
struct magn_3d_state to contain the sensitivity for IIO_ROT.
2. Scale: scale_pre_decml and scale_post_decml are separated for IIO_MAGN
and IIO_ROT.
3. Offset: Same as scale, value_offset is separated for IIO_MAGN and
IIO_ROT.

For sensitivity, HID_USAGE_SENSOR_ORIENT_MAGN_FLUX and
HID_USAGE_SENSOR_ORIENT_MAGN_HEADING are used for sensivitity fields based
on the HID Sensor Usages specifications. Hence, these changes are added on
the sensitivity field.

Subject: staging: lustre: ldlm: change "int" to proper enum type

Fix users of flags that were using "int" instead of named enum.
Rename some "flags" variables to distinguish between different flags.

Subject: staging: lustre: obd: reserve connection flag OBD_CONNECT_FLAGS2

This is a feature for the client and server to use
obd_connect_flags2 to communicate future feature flags. The
client should set this flag whenever any flags in that field
are requested, and the server should mask unsupported features
from this field (assuming it understands OBD_CONNECT_FLAGS2).
When checking if an OBD_CONNECT2_xxxx feature is supported,
the client/server needs to firstly check if OBD_CONNECT_FLAGS2
is supported, since this field is also beyond the end of the
old obd_connect_data.

Land the connection flags to upstream client earlier for reserving
the slot to avoid potential conflict with others.

Subject: staging: most: Eliminate usage of symbolic permissions

Fix checkpatch warnings regarding the use of symbolic permissions.

Where the MOST_CHANNEL_ATTR macro is used, convert to octal
permissions over symbolic.

Where _ATTR is used directly, replace with _ATTR_RW/_ATTR_WO and
update the show/store function names appropriately.

"revId" needs to be unsigned because we use it to test:

and SM750LE_REVISION_ID is ((unsigned char )0xfe).

Subject: staging: dgnc: remove sysfs files

The dgnc driver has no business creating "custom" sysfs files just for a
single tty driver.  Combined with the odd way they are created, it's
just a mess, so remove them entirely as I am tired of tripping over them
when doing driver core changes.

Add init/exit function to follow LKM semantics.
Apparently this module can still load/unload without
the init/exit function.

Tested loading/unloading with and without this patch.

Create headers for pack_generic.c and llog_swab.c
Reference only where needed. This separates out
the kernel only code from lustre_idl.h that is
an UAPI header.

From 884a13694054427b968ac411b76a324f1f442a06 Mon Sep 17 00:00:00 2001
From: Ben Evans <bevans@cray.com>
Date: Fri, 2 Dec 2016 14:40:46 -0500
Subject: staging: lustre: headers: sort headers affected by swab move

It was found if you sort the headers alphabetically
that it reduced patch conflicts. This patch sorts
the headers alphabetically and also place linux
header first, then uapi header and finally the
lustre kernel headers.

At the end of function lstcon_group_info(), "return 0" seems improper.
It may be better to return the value of rc.

Subject: staging: lustre: llite: clear LLIF_DATA_MODIFIED in atomic

This flag should be cleared atomically after the op_data flag
MDS_DATA_MODIFIED is packed. Otherwise, if there exists an
operation to dirty the file again, the state may be missed on
the MDT.

Stop using spin lock lli_lock to protect operations of changing
file flags; using bit operations instead.

Subject: staging: lustre: mdt: race between open and migrate

During intent open, it was found that if the parent has
been migrated to another MDT, it should retry the open
request with the new object, so it needs to keep the
old object in the orphan list, which will be cleanup
during next recovery. Note: if the client still using
the old FID after next recovery, it will return -ENOENT
for the application. Also enqueue the lease lock of
the migrating file, then compare the lease before
migration to make sure no other clients open the file
at the same time.

Subject: staging: lustre: llog: reset llog bitmap

Once update request fails due to eviction or other failures,
all of update request in the sending list should return fail,
because after the failure, the update log in the following
request will have wrong llog bitmap.

Subject: staging: lustre: mdt: fail FMODE_WRITE open if the client is read
 only

O_WRONLY/O_RDWR open on a file will get EROFS on a read only client,
but the rpc gets sent to the mdt anyway.
mdt will increase the mot_write_count of the mdt object, blocking
subsequent FMODE_EXEC open to the same file.

This patch makes sure we fail the FMODE_WRITE open with EROFS on the
client straight away without sending the rpc to mdt.

Subject: staging: lustre: llite: Add client mount opt to ignore suppress_pings

When Lustre servers enable 'suppress_pings', all clients will stop
pinging. However, some clients may not have external mechanism
to notify Lustre servers for node death and therefore need to
preserve the Lustre ping.

This patch provides a mount option 'always_ping' so that the
client will not stop pinging even if the server has enabled
'suppress_pings'.

Subject: staging: lustre: obdclass: limit lu_site hash table size on clients

Allocating a big hash table using the current formula
does not really work for clients. We will create new
hash table for each mount on a single client which is
a lot of memory more than expected.

This patch limits the hash table up to 8M for clients,
which has 524288 entries.

Subject: staging: lustre: statahead: set sai_index_wait with lli_sa_lock held

It is the sponsor thread of the statahead thread to update the
sai::sai_index_wait. Originally, it didn't hold the lli_sa_lock
when did that. Becuase of out-of-order execution others may miss
to wakeup such thread.

On the other hand, if the statahead RPC gets failure, it should
wakeup the sponsor thread, not the statahead thread.

Subject: staging: lustre: clio: remove mtime check in vvp_io_fault_start()

In fault IO initialization, inode's mtime is saved, and after
getting locks, when the IO is about to start, vvp_io_fault_start()
checks the mtime's intactness.

It's a false alarm, since the timestamp from MDS could be stale,
we maintain mtime mainly on OST objects, and if the check in
vvp_io_fault_start() happens before mtime on OST objects are merged,
it will get wrong timestamp from the inode, even the timestamp it
fetched in vvp_io_fault_init() could be wrong in the first place.

This patch remove the mtime check in vvp_io_fault_start().

Subject: staging: lustre: osc: set lock data for readahead lock

If osc_io_readahead() finds a lock that belongs to the previous
instance of osc_object, the lock data pointer will be null. It has
to instantiate with new instance otherwise those pages won't be
destroyed at lock cancel, and then finally hit the assertion in
osc_req_attr_set().

This patch revised dlmlock_at_pgoff() to call osc_match_base() to
find caching locks for readahead. And new osc_object will be set
to the lock if it doesn't have one yet.

Subject: staging: lustre: libcfs: remove lnet upcall code

Removing lnet upcall infrastructure completely
as nobody uses it anymore. The upcall causes a delay
before calling BUG() and might even cause a hang
making getting a crash dump unreliable or containing
outdated info.

Subject: staging: slicoss: remove the staging driver

A "real" driver for this hardware has now landed in the networking tree,
so remove this old staging driver so that we don't have multiple drivers
for the same hardware, and so people don't waste their time trying to
clean up this old code.

Subject: staging/lustre/osc: Revert erroneous list_for_each_entry_safe use

I have been having a lot of unexplainable crashes in osc_lru_shrink
lately that I could not see a good explanation for and then I found
this patch that slip under the radar somehow that incorrectly
converted while loop for lru list iteration into
list_for_each_entry_safe totally ignoring that in the body of
the loop we drop spinlocks guarding this list and move list entries
around.
Not sure why it was not showing up right away, perhaps some of the
more recent LRU changes committed caused some extra pressure on this
code that finally highlighted the breakage.

Subject: staging: dgnc: Fix lines longer than 80 characters

For two cases (beginning and end of the patch) I opted to create small
functions instead of breaking the the lines in a weird way.

The other changes are simple ones: either by breaking the line when
appropriate or by turning a comment into a multi-line one.

Subject: staging/lustre/lnetselftest: Fix potential integer overflow

It looks like if the passed in parameter is not present, but
parameter length is non zero, then sanity checks on the length
are skipped and lstcon_test_add() might then use incorrect
allocation that's prone to integer overflow size.

This patch ensures that parameter len is zero if parameter is
not present.

Subject: staging: comedi: comedidev.h: Document usage of 'detach' handler

Document when the "detach" handler function pointed to by the `detach`
member of a `struct comedi_driver` is called by the comedi core, and how
the "attach" and "auto_attach" handlers can defer clean-up to it when
they return an error to the comedi core.  This is already mentioned as
part of the documentation for `comedi_auto_config()`, but is useful to
document it for `struct comedi_driver` as well, since
`comedi_auto_config()` is not usually called directly by low-level
comedi drivers, and it is not called at all for "legacy" comedi devices
that are configured manually.
