      Pull MFD changes from Samuel Ortiz:
 "Besides the usual cleanups, this one brings:

   * Support for 5 new chipsets: Intel's ICH LPC and SCH Centerton,
     ST-E's STAX211, Samsung's MAX77693 and TI's LM3533.

   * Device tree support for the twl6040, tps65910, da9502 and ab8500
     drivers.

   * Fairly big tps56910, ab8500 and db8500 updates.

   * i2c support for mc13xxx.

   * Our regular update for the wm8xxx driver from Mark."

Fix up various conflicts with other trees, largely due to ab5500 removal
etc.

      Linus Torvalds authored 
      Pull NFS client updates from Trond Myklebust:
 "New features include:
   - Rewrite the O_DIRECT code so that it can share the same coalescing
     and pNFS functionality as the page cache code.
   - Allow the server to provide hints as to when we should use pNFS,
     and when it is more efficient to read and write through the
     metadata server.
   - NFS cache consistency updates:
     * Use the ctime to emulate a change attribute for NFSv2/v3 so that
       all NFS versions can share the same cache management code.
     * New cache management code will only look at the change attribute
       and size attribute when deciding whether or not our cached data
       is still valid or not.
     * Don't request NFSv4 post-op attributes on writes in cases such as
       O_DIRECT, where we don't care about data cache consistency, or
       when we have a write delegation, and know that our cache is still
       consistent.
     * Don't request NFSv4 post-op attributes on operations such as
       COMMIT, where there are no expected metadata updates.
     * Don't request NFSv4 directory post-op attributes in cases where
       the operations themselves already return change attribute
       updates: i.e. operations such as OPEN, CREATE, REMOVE, LINK and
       RENAME.
   - Speed up 'ls' and friends by using READDIR rather than READDIRPLUS
     if we detect no attempts to lookup filenames.
   - Improve the code sharing between NFSv2/v3 and v4 mounts
   - NFSv4.1 state management efficiency improvements
   - More patches in preparation for NFSv4/v4.1 migration functionality."

Fix trivial conflict in fs/nfs/nfs4proc.c that was due to the dcache
qstr name initialization changes (that made the length/hash a 64-bit
union)

      tty: fix ldisc lock inversion trace · 8f6576ad
      Alan Cox authored 
      This is caused by tty_release using tty_lock_pair to lock both sides of
the pty/tty pair, and then tty_ldisc_release dropping and relocking one
side only.  We can drop both fine, so drop both to avoid any lock
ordering concerns.

Rework the release path to fix the new locking model.

      pty: Fix lock inversion · d3ca8b64
      Alan Cox authored 
      The ptmx_open path takes the tty and devpts locks in the wrong order
because tty_init_dev locks and returns a locked tty.  As far as I can
tell this is actually safe anyway because the tty being returned is new
so nobody can get a reference to lock it at this point.

However we don't even need the devpts lock at this point, it's only held
as a byproduct of the way the locks were pushe down.
