If any other driver wants to take precedence over hid-multitouch, the usual way of adding it to hid_have_special_driver will work as the quirk HID_QUIRK_MULTITOUCH won't be set by the generic hid layer.

Allow array field values out of range as per HID 1.11 specification, section 6.2.25: Rather than returning a single bit for each button in the group, an array returns an index in each field that corresponds to the pressed button (like keyboard scan codes). An out-of range value in and array field is considered no controls asserted. Apparently, "and" above is a typo and should be "an". This fixes at least Waltop tablet pen clicks - otherwise BTN_TOUCH is never released.

2012-03-04vfs: move dentry_cmp from <linux/dcache.h> to fs/dcache.cLinus Torvalds
It's only used inside fs/dcache.c, and we're going to play games with it for the word-at-a-time patches. This time we really don't even want to export it, because it really is an internal function to fs/dcache.c, and has been since it was introduced. Having it in that extremely hot header file (it's included in pretty much everything, thanks to <linux/fs.h>) is a disaster for testing different versions, and is utterly pointless. We really should have some kind of header file diet thing, where we figure out which parts of header files are really better off private and only result in more expensive compiles.

2012-03-04mmc: core: Fixup suspend/resume issues for UHS-I cardsUlf Hansson
Even if cards supports 1.8V I/O voltage those should anyway be initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs. Some eMMC and embedded SDIO devices are able to be initialized at 1.8V as well, but it is better to be safe. Do note that initialization in this context means that the card has been completely powered off, otherwise the card will remain at the last I/O voltage level that were negotitiated. Due to the above being taken care of the suspend/resume issues for UHS-I SD-cards has been fixed.

2012-03-04mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5Sascha Hauer
On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION command. This works for SD cards. However, with MMC cards the MMC_SET_BLOCK_COUNT command is used instead, but this needs the same handling. Fix MMC cards by testing for the MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53 board with a Transcend MMC+ card and eMMC. The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this is a regression for these boards introduced in 3.0; it should go to 3.0/3.1/3.2-stable.

2012-03-04mmc: core: fix regression: set default clock gating delay to 0Guennadi Liakhovetski
A recent commit "mmc: core: Use delayed work in clock gating framework" (597dd9d79cfbbb1) introduced a default 200ms delay before clock gating actually takes place. This means that every time an MMC interface becomes idle it first stays on for 200ms before gating its clock. This leads to increased power consumption and is therefore a clear regression. This patch restores the original behaviour by setting the default delay to 0. Users prioritising throughput over power efficiency can still modify the delay via sysfs.

2012-03-02vfs: split up name hashing in link_path_walk() into helper functionLinus Torvalds
The code in link_path_walk() that finds out the length and the hash of the next path component is some of the hottest code in the kernel. And I have a version of it that does things at the full width of the CPU wordsize at a time, but that means that we *really* want to split it up into a separate helper function. So this re-organizes the code a bit and splits the hashing part into a helper function called "hash_name()". It returns the length of the pathname component, while at the same time computing and writing the hash to the appropriate location. The code generation is slightly changed by this patch, but generally for the better - and the added abstraction actually makes the code easier to read too. And the new interface is well suited for replacing just the "hash_name()" function with alternative implementations. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-02vfs: clarify and clean up dentry_cmp()Linus Torvalds

.. and also use it in lookup_one_len() rather than open-coding it. There aren't any performance-critical users, so inlining it is silly. But it wouldn't matter if it wasn't for the fact that the word-at-a-time dentry name patches want to conditionally replace the function, and uninlining it sets the stage for that. So again, this is a preparatory patch that doesn't change any semantics, and only prepares for a much cleaner and testable word-at-a-time dentry name accessor patch.

2012-03-02hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enableNikolaus Schulz
The F75387 supports automatic fan control using either PWM duty cycle or RPM speed values. Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.

It turned out that a performance counter on AMD does not count at all when the GO or HO bit is set in the control register and SVM is disabled in EFER. This patch works around this issue by masking out the HO bit in the performance counter control register when SVM is not enabled. The GO bit is not touched because it is only set when the user wants to count in guest-mode only. So when SVM is disabled the counter should not run at all and the not-counting is the intended behaviour.
