c862868bb4 ceph: move encode_fh to new API
Use parent_inode has a flag for whether nfsd wants a connectable fh, but
generate one opportunistically so that we can take advantage of the

b0b0382bb4 ->encode_fh() API change
pass inode + parent's inode or NULL instead of dentry + bool saying
whether we want the parent or not.

53f2c4a8fd NFS client updates for Linux 3.5
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.

8f6576ad47 tty: fix ldisc lock inversion trace
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.

d3ca8b64b9 pty: Fix lock inversion
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.

fb13bfa7e1 NFSv4: Map NFS4ERR_SHARE_DENIED into an EACCES error instead of EIO
If a file OPEN is denied due to a share lock, the resulting
NFS4ERR_SHARE_DENIED is currently mapped to the default EIO.
This patch adds a more appropriate mapping, and brings Linux
into line with what Solaris 10 does.

359d7d1c97 NFSv4: update_changeattr does not need to set NFS_INO_REVAL_PAGECACHE
We're already invalidating the data cache, and setting the new change
attribute. Since directories don't care about the i_size field, there
is no need to be forcing any extra revalidation of the page cache.

We do keep the NFS_INO_INVALID_ATTR flag, in order to force an
attribute cache revalidation on stat() calls since we do not
update the mtime and ctime fields.

The aligned_byte_mask() definition is wrong for 32-bit big-endian

1e2aec873a Merge branch 'generic-string-functions'
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

ae32adc1e0 Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
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."

Fixed up trivial conflict in arch/arm/mach-lpc32xx/common.c due to the
same patch already having come in through the arm/soc trees, with
additional patches on top of it.

f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

2c757fd5d1 arm-soc: cleanups, part 2
More cleanups, continuing an earlier set with omap and samsung specific
 cleanups. These could not go into the first set because they have
 dependencies on various other series that in turn depend on the first
 cleanups.

Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

 "More cleanups, continuing an earlier set with omap and samsung
  specific cleanups.  These could not go into the first set because they
  have dependencies on various other series that in turn depend on the
  first cleanups."

Fixed up conflicts in arch/arm/plat-omap/counter_32k.c due to commit
bd0493eaaf: "move read_{boot,persistent}_clock to the architecture
level" that changed how the persistent clocks were handled.  And trivial
conflicts in arch/arm/mach-omap1/common.h due to just independent
changes close to each other.

ce53044c68 arm-soc: driver specific updates
These changes are specific to some driver that may be used by multiple
 boards or socs. The most significant change in here is the move of the
 samsung iommu code from a platform specific in-kernel interface to the
 generic iommu subsystem.
