Pull xfs fixes from Dave Chinner:
 "This is the first pull request I've had to do for you, so I'm still
  sorting things out.  The reason I'm sending this and not Ben should be
  obvious from the first commit below - SGI has stepped down from the
  XFS maintainership role.  As such, I'd like to take another
  opportunity to thank them for their many years of effort maintaining
  XFS and supporting the XFS community that they developed from the
  ground up.

  So I haven't had time to work things like signed tags into my
  workflows yet, so this is just a repo branch I'm asking you to pull
  from.  And yes, I named the branch -rc4 because I wanted the fixes in
  rc4, not because the branch was for merging into -rc3.  Probably not
  right, either.

  Anyway, I should have everything sorted out by the time the next merge
  window comes around.  If there's anything that you don't like in the
  pull req, feel free to flame me unmercifully.

  The changes are fixes for recent regressions and important thinkos in
  verification code:

        - a log vector buffer alignment issue on ia32
        - timestamps on truncate got mangled
        - primary superblock CRC validation fixes and error message
          sanitisation"

Pull devicetree fixes from Grant Likely:
 "Device tree compatible match order bug fix

  This branch contains a bug fix for the way devicetree code identifies
  the type of device.  Device drivers can contain a list of
  of_device_ids, but it more than one entry will match, then the device
  driver may choose the wrong one.  Commit 10535314, "match each node
  compatible against all given matches first", was queued for v3.14 but
  ended up causing other bugs.  Commit 06b29e76 attempted to fix it
  but it had other bugs.  Merely reverting the fix and waiting until
  v3.15 isn't a good option because there is code in v3.14 that depends
  on the revised behaviour to boot.

  This branch should finally fixes the problem correctly.  This time
  instead of just hoping that the patch is correct, this branch also
  adds new testcases that validate the behaviour.

  The changes in this branch are larger than I would like for a -rc
  pull, but moving the test case data out of out of arch/arm so that it
  could be validated on other architectures was important"

   - I ran the driver on a system where the SMMU is hooked into a
     coherent interconnect for table walks, and noticed a shareability
     mismatch between the CPU and the SMMU

pretty though. A useful project would be to make the testcase code

In the current implementation of __of_match_node(), it will compare
each given match entry against all the node's compatible strings
with of_device_is_compatible().

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and
also an alphabetical ordering is more sane there.

Therefore, we define a following priority order for the match, and
then scan all the entries to find the best match.
  1. specific compatible && type && name
  2. specific compatible && type
  3. specific compatible && name
  4. specific compatible
  5. general compatible && type && name
  6. general compatible && type
  7. general compatible && name
  8. general compatible
  9. type && name
  10. type
  11. name

    entry, but it doesn't match with the device node's compatible.

ASoC: Fixes for v3.14

A few fixes, all driver speccific ones.  The DaVinci ones aren't as
clear as they should be from the subject lines on the commits but they
fix issues which will prevent correct operation in some use cases and
only affect that particular driver so are reasonably safe.

While copy_to/from_user_page() users are uncommon, there is one in
drivers/staging/lustre/lustre/libcfs/linux/linux-curproc.c which leads
to the following:

ERROR: "sparc32_cachetlb_ops" [drivers/staging/lustre/lustre/libcfs/libcfs.ko] undefined!

during routine allmodconfig build coverage.  The reason this happens
is as follows:

In arch/sparc/include/asm/cacheflush_32.h we have:

 #define flush_cache_page(vma,addr,pfn) \
        sparc32_cachetlb_ops->cache_page(vma, addr)

 #define copy_to_user_page(vma, page, vaddr, dst, src, len) \
        do {                                                    \
                flush_cache_page(vma, vaddr, page_to_pfn(page));\
                memcpy(dst, src, len);                          \
        } while (0)
 #define copy_from_user_page(vma, page, vaddr, dst, src, len) \
        do {                                                    \
                flush_cache_page(vma, vaddr, page_to_pfn(page));\
                memcpy(dst, src, len);                          \
        } while (0)

However, sparc32_cachetlb_ops isn't exported and hence the error.

In arch/sparc/Kernel/Makefile, we see:

However, the Kconfig selects HAVE_ARCH_JUMP_LABEL unconditionally

doing allmodconfig coverage builds:

Some system's ACPI video backlight control interface is broken and the
native backlight control interface should be used by default. This patch
sets the use_native_backlight parameter to true for those systems so
that video backlight control interface will not be created. For detailed
models that are added here, reference the following list.

Note that the user specified kernel cmdline option will always have the
highest priority, i.e. if use_native_backlight=0 is specified and the
system is in the DMI table, the video module will not skip registering
backlight interface for it.

Some devices have duplicate entries in there brightness levels table, ie
on my Dell Latitude E6430 the table looks like this:

[    3.686060] acpi backlight index   0, val 80
[    3.686095] acpi backlight index   1, val 50
[    3.686122] acpi backlight index   2, val 5
[    3.686147] acpi backlight index   3, val 5
[    3.686172] acpi backlight index   4, val 5
[    3.686197] acpi backlight index   5, val 5
[    3.686223] acpi backlight index   6, val 5
[    3.686248] acpi backlight index   7, val 5
[    3.686273] acpi backlight index   8, val 6
[    3.686332] acpi backlight index   9, val 7
[    3.686356] acpi backlight index  10, val 8
[    3.686380] acpi backlight index  11, val 9
etc.

Notice that brightness values 0-5 are all mapped to 5. This means that
if userspace writes any value between 0 and 5 to the brightness sysfs attribute
and then reads it, it will always return 0, which is somewhat unexpected.

This is a problem for ie gnome-settings-daemon, which uses read-modify-write
logic when the users presses the brightness up or down keys. This is done
this way to take brightness changes from other sources into account.

On this specific laptop what happens once the brightness has been set to 0,
is that gsd reads 0, adds 5, writes 5, and on the next brightness up key press
again reads 0, so things get stuck at the lowest brightness setting.

Filtering out the duplicate table entries, makes any write to brightness
read back as the written value as one would expect, fixing this.

Pull NFS client bugfixes from Trond Myklebust:
 "Highlights include stable fixes for the following bugs:

   - General performance regression due to NFS_INO_INVALID_LABEL being
     set when the server doesn't support labeled NFS
   - Hang in the RPC code due to a socket out-of-buffer race
   - Infinite loop when trying to establish the NFSv4 lease
   - Use-after-free bug in the RPCSEC gss code.
   - nfs4_select_rw_stateid is returning with a non-zero error value on
     success

  Other bug fixes:

  - Potential memory scribble in the RPC bi-directional RPC code
  - Pipe version reference leak
  - Use the correct net namespace in the new NFSv4 migration code"

* tag 'nfs-for-3.14-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
  NFS fix error return in nfs4_select_rw_stateid
  NFSv4: Use the correct net namespace in nfs4_update_server
  SUNRPC: Fix a pipe_version reference leak
  SUNRPC: Ensure that gss_auth isn't freed before its upcall messages
  SUNRPC: Fix potential memory scribble in xprt_free_bc_request()
  SUNRPC: Fix races in xs_nospace()
  SUNRPC: Don't create a gss auth cache unless rpc.gssd is running
  NFS: Do not set NFS_INO_INVALID_LABEL unless server supports labeled NFS

Pull MFD fixes from Lee Jones:
 "Couple of small issues solved:
   - Suspend/Resume call-backs require CONFIG_PM_SLEEP
   - Some drivers written for 32bit architectures fail when compiled
     with a 64bit compiler.  The fixes will future proof the drivers"

* tag 'mfd-fixes-3.14-1' of git://git.linaro.org/people/lee.jones/mfd:
  mfd: sec-core: sec_pmic_{suspend,resume}() should depend on CONFIG_PM_SLEEP
  mfd: max14577: max14577_{suspend,resume}() should depend on CONFIG_PM_SLEEP
