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."

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.

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.

This makes <asm/word-at-a-time.h> actually live up to its promise of
allowing architectures to help tune the string functions that do their
work a word at a time.

David had already taken the x86 strncpy_from_user() function, modified
it to work on sparc, and then done the extra work to make it generically
useful.  This then expands on that work by making x86 use that generic
version, completing the circle.

But more importantly, it fixes up the word-at-a-time interfaces so that
it's now easy to also support things like strnlen_user(), and pretty
much most random string functions.

David reports that it all works fine on sparc, and Jonas Bonn reported
that an earlier version of this worked on OpenRISC too.  It's pretty
easy for architectures to add support for this and just replace their
private versions with the generic code.

* generic-string-functions:
  sparc: use the new generic strnlen_user() function
  x86: use the new generic strnlen_user() function
  lib: add generic strnlen_user() function
  word-at-a-time: make the interfaces truly generic
  x86: use generic strncpy_from_user routine

After 303395ac, some headers are

Pull i2c-embedded changes from Wolfram Sang:
 "Major changes:

   - lots of devicetree additions for existing drivers.  I tried hard to
     make sure the bindings are proper.  In more complicated cases, I
     requested acks from people having more experience with them than
     me.  That took a bit of extra time and also some time went into
     discussions with developers about what bindings are and what not.
     I have the feeling that the workflow with bindings should be
     improved to scale better.  I will spend some more thought on
     this...

   - i2c-muxes are succesfully used meanwhile, so we dropped
     EXPERIMENTAL for them and renamed the drivers to a standard pattern
     to match the rest of the subsystem.  They can also be used with
     devicetree now.

   - ixp2000 was removed since the whole platform goes away.

   - cleanups (strlcpy instead of strcpy, NULL instead of 0)

   - The rest is typical driver fixes I assume.

  All patches have been in linux-next at least since v3.4-rc6."
