Check for regmap_read() return code before using the read value in
following write in exynos5_switch_timing_regs(). Pass reading error
code to the callers.
This does not introduce proper error handling for such failed reads (and
obviously regmap_write() error is still ignored) because the driver
ignored this in all places. Therefor it only fixes reported issue while
matching current driver coding style:
drivers/memory/samsung/exynos5422-dmc.c: In function 'exynos5_switch_timing_regs':

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
larger refactoring of the Designware, Tegra, and PXA drivers, the
Cadence driver supports being a slave now, and there is support to
instanciate SPD eeproms for well-known cases (which will be
user-visible because the i801 driver supports it), and some
devm_platform_ioremap_resource() conversions which blow up the
diffstat.
Note that I applied the Nuvoton driver quite late, so some minor fixup
patches arrived during the merge window. I chose to apply them right

Pull x86 entry updates from Thomas Gleixner:
"The x86 entry, exception and interrupt code rework
This all started about 6 month ago with the attempt to move the Posix
CPU timer heavy lifting out of the timer interrupt code and just have
lockless quick checks in that code path. Trivial 5 patches.
This unearthed an inconsistency in the KVM handling of task work and
the review requested to move all of this into generic code so other
architectures can share.
Valid request and solved with another 25 patches but those unearthed
inconsistencies vs. RCU and instrumentation.
Digging into this made it obvious that there are quite some
inconsistencies vs. instrumentation in general. The int3 text poke
handling in particular was completely unprotected and with the batched
update of trace events even more likely to expose to endless int3
recursion.
In parallel the RCU implications of instrumenting fragile entry code
came up in several discussions.
The conclusion of the x86 maintainer team was to go all the way and
make the protection against any form of instrumentation of fragile and
dangerous code pathes enforcable and verifiable by tooling.
A first batch of preparatory work hit mainline with commit
d5f744f9a2ac ("Pull x86 entry code updates from Thomas Gleixner")
That (almost) full solution introduced a new code section
'.noinstr.text' into which all code which needs to be protected from
instrumentation of all sorts goes into. Any call into instrumentable
code out of this section has to be annotated. objtool has support to
validate this.
Kprobes now excludes this section fully which also prevents BPF from
fiddling with it and all 'noinstr' annotated functions also keep
ftrace off. The section, kprobes and objtool changes are already
merged.
The major changes coming with this are:
- Preparatory cleanups
- Annotating of relevant functions to move them into the
noinstr.text section or enforcing inlining by marking them
__always_inline so the compiler cannot misplace or instrument
them.
- Splitting and simplifying the idtentry macro maze so that it is
now clearly separated into simple exception entries and the more
interesting ones which use interrupt stacks and have the paranoid
handling vs. CR3 and GS.
- Move quite some of the low level ASM functionality into C code:
- enter_from and exit to user space handling. The ASM code now
calls into C after doing the really necessary ASM handling and
the return path goes back out without bells and whistels in
ASM.
- exception entry/exit got the equivivalent treatment
- move all IRQ tracepoints from ASM to C so they can be placed as
appropriate which is especially important for the int3
recursion issue.
- Consolidate the declaration and definition of entry points between
32 and 64 bit. They share a common header and macros now.
- Remove the extra device interrupt entry maze and just use the
regular exception entry code.
- All ASM entry points except NMI are now generated from the shared
header file and the corresponding macros in the 32 and 64 bit
entry ASM.
- The C code entry points are consolidated as well with the help of
DEFINE_IDTENTRY*() macros. This allows to ensure at one central
point that all corresponding entry points share the same
semantics. The actual function body for most entry points is in an
instrumentable and sane state.
There are special macros for the more sensitive entry points, e.g.
INT3 and of course the nasty paranoid #NMI, #MCE, #DB and #DF.
They allow to put the whole entry instrumentation and RCU handling
into safe places instead of the previous pray that it is correct
approach.
- The INT3 text poke handling is now completely isolated and the
recursion issue banned. Aside of the entry rework this required
other isolation work, e.g. the ability to force inline bsearch.
- Prevent #DB on fragile entry code, entry relevant memory and
disable it on NMI, #MC entry, which allowed to get rid of the
nested #DB IST stack shifting hackery.
- A few other cleanups and enhancements which have been made
possible through this and already merged changes, e.g.
consolidating and further restricting the IDT code so the IDT
table becomes RO after init which removes yet another popular
attack vector
- About 680 lines of ASM maze are gone.
There are a few open issues:
- An escape out of the noinstr section in the MCE handler which needs
some more thought but under the aspect that MCE is a complete
trainwreck by design and the propability to survive it is low, this
was not high on the priority list.
- Paravirtualization
When PV is enabled then objtool complains about a bunch of indirect
calls out of the noinstr section. There are a few straight forward
ways to fix this, but the other issues vs. general correctness were
more pressing than parawitz.
- KVM
KVM is inconsistent as well. Patches have been posted, but they
have not yet been commented on or picked up by the KVM folks.
- IDLE
Pretty much the same problems can be found in the low level idle
code especially the parts where RCU stopped watching. This was
beyond the scope of the more obvious and exposable problems and is
on the todo list.
The lesson learned from this brain melting exercise to morph the
evolved code base into something which can be validated and understood
is that once again the violation of the most important engineering
principle "correctness first" has caused quite a few people to spend
valuable time on problems which could have been avoided in the first
place. The "features first" tinkering mindset really has to stop.
With that I want to say thanks to everyone involved in contributing to
this effort. Special thanks go to the following people (alphabetical
order): Alexandre Chartre, Andy Lutomirski, Borislav Petkov, Brian
Gerst, Frederic Weisbecker, Josh Poimboeuf, Juergen Gross, Lai

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the

Pull the Kernel Concurrency Sanitizer from Thomas Gleixner:
"The Kernel Concurrency Sanitizer (KCSAN) is a dynamic race detector,
which relies on compile-time instrumentation, and uses a
watchpoint-based sampling approach to detect races.
The feature was under development for quite some time and has already
found legitimate bugs.
Unfortunately it comes with a limitation, which was only understood
late in the development cycle:
It requires an up to date CLANG-11 compiler
CLANG-11 is not yet released (scheduled for June), but it's the only
compiler today which handles the kernel requirements and especially
the annotations of functions to exclude them from KCSAN
instrumentation correctly.
These annotations really need to work so that low level entry code and
especially int3 text poke handling can be completely isolated.
A detailed discussion of the requirements and compiler issues can be
found here:
https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/
We came to the conclusion that trying to work around compiler
limitations and bugs again would end up in a major trainwreck, so
requiring a working compiler seemed to be the best choice.
For Continous Integration purposes the compiler restriction is
manageable and that's where most xxSAN reports come from.
For a change this limitation might make GCC people actually look at
their bugs. Some issues with CSAN in GCC are 7 years old and one has
been 'fixed' 3 years ago with a half baken solution which 'solved' the
reported issue but not the underlying problem.
The KCSAN developers also ponder to use a GCC plugin to become
independent, but that's not something which will show up in a few
days.
Blocking KCSAN until wide spread compiler support is available is not
a really good alternative because the continuous growth of lockless
optimizations in the kernel demands proper tooling support"

Only QMAP endpoints should be configured to find a pad size field
within packet headers. They are found in the first byte of the QMAP
header (and the hardware fills only the 6 bits in that byte that
constitute the pad_len field).
The RMNet driver assumes the pad_len field is valid for received
packets, so we want to ensure the pad_len field is filled in that
case. That driver also assumes the length in the QMAP header
includes the pad bytes.
The RMNet driver does *not* pad the packets it sends, so the pad_len
field can be ignored.
Fix ipa_endpoint_init_hdr_ext() so it only marks the pad field
offset valid for QMAP RX endpoints, and in that case indicates
that the length field in the header includes the pad bytes.

The upper two nibbles of the sequencer type were not used for
SDM845, and were assumed to be 0. But for SC7180 they are used, and
so they must be programmed by ipa_endpoint_init_seq(). Fix this bug.

The way the mask value is programmed for QMAP RX endpoints was based
on some wrong assumptions about the way metadata containing the QMAP
mux_id value is formatted. The metadata value supplied by the
modem is *not* in QMAP format, and in fact contains the mux_id we
want in its (big endian) low-order byte. That byte must be written
by the IPA into offset 1 of the QMAP header it inserts before the
received packet.
QMAP TX endpoints *do* use a QMAP header as the metadata sent with
each packet. The modem assumes this, and based on that assumes the
mux_id is in the second byte. To match those assumptions we must
program the modem TX (QMAP) endpoint HDR register to indicate the
metadata will be found at offset 0 in the message header.
The previous configuration managed to work, but it was not working
correctly. This patch fixes a bug whose symptom was receipt of
messages containing the wrong QMAP mux_id.
In fixing this, get rid of ipa_rmnet_mux_id_metadata_mask(), which
was more or less defined so there was a separate place to explain
what was happening as we generated the mask value. Instead, put a
longer description of how this works above ipa_endpoint_init_hdr(),
and define the metadata mask to use as a simple constant.

Brett fixes the supported link speeds in the iavf driver, which was only
able to report speeds that the i40e driver supported and was missing the
speeds supported by the ice driver. In addition, fix how 2.5 and 5.0
GbE speeds are reported.
Alek fixes a enum comparison that was comparing two different enums that
may have different values, so update the comparison to use matching
enums.
Paul increases the time to complete a reset to allow for 128 VFs to
complete a reset.

Current below problems exists.
1. devlink device is registered by mlx5_load_one(). But it is
not unregistered by mlx5_unload_one(). This is incorrect.
2. Above issue leads to,
When mlx5 PCI device is removed, currently devlink device is
unregistered before devlink ports are unregistered in below ladder
diagram.
remove_one()
mlx5_devlink_unregister()
[..]
devlink_unregister() <- ports are still registered!
mlx5_unload_one()
mlx5_unregister_device()
mlx5_remove_device()
mlx5e_remove()
mlx5e_devlink_port_unregister()
devlink_port_unregister()
3. Condition checking for registering and unregister device are not
symmetric either in these routines.
Hence, fix the sequence by having load and unload routines symmetric
and in right order.
i.e.
(a) register devlink device followed by registering devlink ports
(b) unregister devlink ports followed by devlink device
Do this based on boot and cleanup flags instead of different
conditions.

After an XSK is closed, the relevant structures in the channel are not
zeroed. If an XSK is opened the second time on the same channel without
recreating channels, the stray values in the structures will lead to
incorrect operation of queues, which causes CQE errors, and the new
socket doesn't work at all.
This patch fixes the issue by explicitly zeroing XSK-related structs in
the channel on XSK close. Note that those structs are zeroed on channel
creation, and usually a configuration change (XDP program is set)
happens on XSK open, which leads to recreating channels, so typical XSK
usecases don't suffer from this issue. However, if XSKs are opened and
closed on the same channel without removing the XDP program, this bug
reproduces.

several minutes until commands will get timeouts, because these commands

Commit 4ae4916b5643 ("i40e: fix 'Unknown bps' in dmesg for 2.5Gb/5Gb
speeds") added the ability for the PF to report 2.5 and 5Gb speeds,
however, the iavf driver does not recognize those speeds as the values were
not added there. Add the proper enums and values so that iavf can properly
deal with those speeds.

adapter->link_speed has type enum virtchnl_link_speed but our comparisons
are against enum iavf_aq_link_speed. Though they are, currently, the same
values, change the comparison to the matching enum virtchnl_link_speed
since that may not always be the case.

Link speeds are communicated over virtchnl using an enum
virtchnl_link_speed. Currently, the highest link speed is 40Gbps which
leaves us unable to reflect some speeds that an ice VF is capable of.
This causes link speed to be misreported on the iavf driver.
Allow for communicating link speeds using Mbps so that the proper speed can
be reported for an ice VF. Moving away from the enum allows us to
communicate future speed changes without requiring a new enum to be added.
In order to support communicating link speeds over virtchnl in Mbps the
following functionality was added:
- Added u32 link_speed_mbps in the iavf_adapter structure.
- Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF
driver supports communicating link speeds in Mbps.
- Added the function iavf_get_vpe_link_status() to fill the
correct link_status in the event_data union based on the
ADV_LINK_SUPPORT(_a) macro.
- Added the function iavf_set_adapter_link_speed_from_vpe()
to determine whether or not to fill the u32 link_speed_mbps or
enum virtchnl_link_speed link_speed field in the iavf_adapter
structure based on the ADV_LINK_SUPPORT(_a) macro.
- Do not free vf_res in iavf_init_get_resources() as vf_res will be
accessed in iavf_get_link_ksettings(); memset to 0 instead. This
memory is subsequently freed in iavf_remove().
