The test run took a while and hasn't finished after close to 2 hours. The crash happened right after I gave up and killed the test (after 107m) with Ctrl+C." The crash happened because a NULL inode pointer got passed into locks_get_lock_context. The call chain indicates that file_inode(filp) returned NULL, which means that f_inode was NULL. Since that's zeroed out in __fput, that suggests that this filp pointer outlived the last reference. Looking at the code, that seems possible. We copy the struct file_lock that's passed in, but if the task is signalled at an inopportune time we can end up trying to use that file_lock in rpciod context after the process that requested it has already returned (and possibly put its filp reference). Fix this by taking an extra reference to the filp when we allocate the lock info, and put it in nfs4_lock_release.

2015-05-13nfs: stat(2) fails during cthon04 basic test5 on NFSv4.0Chuck Lever
When running the Connectathon basic tests against a Solaris NFS server over NFSv4.0, test5 reports that stat(2) returns a file size of zero instead of 1MB. On success, nfs_commit_inode() can return a positive result; see other call sites such as nfs_file_fsync_commit() and nfs_commit_unstable_pages(). The call site recently added in nfs_wb_all() does not prevent that positive return value from leaking to its callers. If it leaks through nfs_sync_inode() back to nfs_getattr(), that causes stat(2) to return a positive return value to user space while also not filling in the passed-in struct stat. Additional clean up: the new logic in nfs_wb_all() is rewritten in bfields-normal form. Fixes: 5bb89b4702e2 ("NFSv4.1/pnfs: Separate out metadata . . .")

Second version of this pull request as a small fix to a fix turned up before Greg pulled it for a cc10001 patch near the top of the tree. One core fix * Set updated for a iio kfifo was incorrectly set to false during a failed update, resulting in atttempts to repeat the failed operation appearing to succeed. This time I've decided to list the driver fixes in alphabetical order rather than 'randomly'. * axp288_adc - a recent change added a check for valid info masks when reading channels from consumer drivers. * bmp280 - temperature compensation was failing to read the tfine value, hence causing a temperature of 0 to always be returned and incorrect presure measurements. * cc10001 - Fix channel number mapping when some channels are reserved for remote CPUs. Fix an issue with the use of the power-up/power-down register (basically wrong polarity). Fix an issue due to the missinterpretting the return value from regulator_get_voltage. Add a delay before the start bit as recommended for the hardware to avoid data corruption. * hid pressure - fix channel spec of modfiied, but no modifier (which makes no sense!) * hid proximity - fix channel spec of modified, but no modifier (which makes no sense!). Fix a memory leak in the probe function. * mcp320x - occasional incorrect readings on dma using spi busses due to cacheline corruption. Fixed by forcing ___cacheline_aligned for the buffers. * mma9551 - buffer overrun fix (miss specified maximum length of buffers) * mma9553 - endian fix on status message. Add an enable element for activity channel. Input checking for activity period to avoid rather unpredictable results. * spmi-vadc - fix an overflow in the output value normalization seen on some boards. * st-snesors - oops due to use of a mutex that is not yet initialized during probe. * xilinx adc - Some wrong register addresses, a wrong address for vccaux channel, incorrect scale on VREFP and incorrect sign on VREFN.
2015-05-13Input: elantech - fix semi-mt protocol for v3 HWBenjamin Tissoires
When the v3 hardware sees more than one finger, it uses the semi-mt protocol to report the touches. However, it currently works when num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1 finger as if num_fingers was 1. This confuses userspace which knows how to deal with extra fingers when all the slots are used, but not when some are missing.

2015-05-13ktime: Fix ktime_divns to do signed divisionJohn Stultz
It was noted that the 32bit implementation of ktime_divns() was doing unsigned division and didn't properly handle negative values. And when a ktime helper was changed to utilize ktime_divns, it caused a regression on some IR blasters. See the following bugzilla for details: https://bugzilla.redhat.com/show_bug.cgi?id=1200353 This patch fixes the problem in ktime_divns by checking and preserving the sign bit, and then reapplying it if appropriate after the division, it also changes the return type to a s64 to make it more obvious this is expected. Nicolas also pointed out that negative dividers would cause infinite loops on 32bit systems, negative dividers is unlikely for users of this function, but out of caution this patch adds checks for negative dividers for both 32-bit (BUG_ON) and 64-bit(WARN_ON) versions to make sure no such use cases creep in.

2015-05-12net: phy: micrel: Fix regression in kszphy_probeNiklas Cassel
Don't do clock-mode-select if clk == NULL, since when building without CONFIG_HAVE_CLK, clk_get returns NULL and clk_get_rate returns 0. Doing clock-mode-select in this cause causes kszphy_probe to return -EINVAL and thus prevents the device from being probed. The original code (before regression) would return 0 when building without CONFIG_HAVE_CLK.

Fix "BUG: using smp_processor_id() in preemptible" reported in accesses to thread's FPU defaults: the value to initialise FSCR to at program startup, the FCSR r/w mask and the contents of FIR in full FPU emulation, removing a regression introduced with 9b26616c [MIPS: Respect the ISA level in FCSR handling] and f6843626 [MIPS: math-emu: Set FIR feature flags for full emulation]. Use `boot_cpu_data' to obtain the data from, following the approach that `cpu_has_*' macros take and avoiding the call to `smp_processor_id' made in the reference to `current_cpu_data'. The contents of FSCR have to be consistent across processors in an SMP system, the settings there must not change as a thread is migrated across processors. And the contents of FIR are guaranteed to be consistent in FPU emulation, by definition. Signed-off-by: Maciej W.
