2011-05-26ARM: 6832/1: mmci: support for ST-Ericsson db8500v2Philippe Langlais
ST-Ericsson modified ARM PrimeCell PL180 block has not got an updated corresponding amba-id, althought the IP block has changed in db8500v2. The change was done to the datactrl register. Using the overrided subversion ID, account for this.

2011-05-26ARM: 6829/1: amba: make hardcoded periphid override hardwareLinus Walleij
This makes a hardcoded periphid from the platform override any magic number found in the hardware. This shall henceforth be used when the information found in the hardware is either missing, i.e. not encoding the CID with the magic cookie 0xb105f00d, or incorrect such that the revision number should have been bumped in hardware, but the silicon designer has failed to do so.

The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: jtluka@redhat.com CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: nicolas.2p.debian@gmail.com CC: "David S.

2011-05-25via-velocity: don't annotate MAC registers as packedUlrich Hecht
On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: David S.

2011-05-25mmc: core: eMMC bus width may not work on all platformsPhilip Rakity
CMD19 -- The offical way to validate bus widths from the JEDEC spec does not work on all platforms. Some platforms that use PCI/PCIe to connect their SD controllers are known to fail. If the quirk MMC_BUS_WIDTH_TEST is not defined we try to figure out the bus width by reading the ext_csd at different bus widths and compare this against the ext_csd read in 1 bit mode. If no ext_csd is available we default to 1 bit operations. Code has been tested on mmp2 against 8 bit eMMC and Transcend 2GB card that is known to not work in 4 bit mode. The physical pins on the card are not present to support 4 bit operation. Signed-off-by: Philip Rakity <prakity@marvell.com> Signed-off-by: Chris Ball <cjb@laptop.org>

2011-05-25hwmon: (abituguru) Depend on DMIJean Delvare
The abituguru drivers are only built on X86, where DMI support is now enabled by default. So let these drivers depend on DMI, for the following gains: * Robustness and safety. Detection of these devices is weak and uses non-standard methods, it should really be limited to Abit boards unless the user explicitly asks otherwise. * Code simplicity. The code is easier to read without ifdefs. * Better build testing coverage. Now there's only one way to build the drivers, so no risk of build failure on exotic systems.

2011-05-25hwmon: (max6650) Drop device detectionJean Delvare
MAX6650 device detection is unreliable, we got reports of false positives. We now have many ways to let users instantiate the devices explicitly, so unreliable detection should be dropped.

2011-05-25Move ACPI power meter driver to hwmonJean Delvare
As discussed earlier, the ACPI power meter driver would better live in drivers/hwmon, as its only purpose is to create hwmon-style interfaces for ACPI 4.0 power meter devices. Users are more likely to look for it there, and less likely to accidentally hide it by unselecting its dependencies. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: "Darrick J.

2011-05-25hwmon: (asc7621) Drop duplicate dependencyJean Delvare
The config SENSORS_ASC7621 entry is inside an if HWMON / endif block, so it already depends on HWMON. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-05-25hwmon: (jc42) Change detection classJean Delvare
While the JC42-compatible chips are temperature sensors, I2C_CLASS_SPD makes more sense because these chips always live on memory modules. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Guenter Roeck <guenter.roeck@ericsson.com>
2011-05-25hwmon: Add driver for AMD family 15h processor power informationAndreas Herrmann
This CPU family provides NB register values to gather following TDP information * ProcessorPwrWatts: Specifies in Watts the maximum amount of power the processor can support. * CurrPwrWatts: Specifies in Watts the current amount of power being consumed by the processor. This driver provides * power1_crit (ProcessorPwrWatts) * power1_input (CurrPwrWatts) Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2011-05-25hwmon: (k10temp) Add support for Fam15h (Bulldozer)Andre Przywara
AMDs upcoming CPUs use the same mechanism for the internal temperature reporting as the Fam10h CPUs, so we just needed to add the appropriate PCI-ID to the list. This allows to use the k10temp driver on those CPUs. While at it change the Kconfig entry to be more generic.

2011-05-25i8k: Avoid lahf in 64-bit codeLuca Tettamanti
i8k uses lahf to read the flag register in 64-bit code; early x86-64 CPUs, however, lack this instruction and we get an invalid opcode exception at runtime. Use pushf to load the flag register into the stack instead.
