   - Fix workarounds for R4000 erratum.
   - Patch up DEC, Siemens-Nixdorf and Loongson hardware support.
   - Wire up renameat2 syscall.
   - Delete unused file - it was causing false warnings from maintenance
     scripts.
   - Revert a patch because it's functionality is now implemented twice
     which causes superfluous /proc/cpuinfo output.
   - Fix a microMIPS regression"

_STK_LIM_MAX could be used to override the RLIMIT_STACK hard limit from
an arch's include/uapi/asm-generic/resource.h file, but is no longer
used since both parisc and metag removed the override. Therefore remove
it entirely, setting the hard RLIMIT_STACK limit to RLIM_INFINITY
directly in include/asm-generic/resource.h.

A MIPS64 kernel may support ELF files for all 3 MIPS ABIs
(O32, N32, N64). Furthermore, the AUDIT_ARCH_MIPS{,EL}64 token
does not provide enough information about the ABI for the 64-bit
process. As a result of which, userland needs to use complex
seccomp filters to decide whether a syscall belongs to the o32 or n32
or n64 ABI. Therefore, a new arch token for MIPS64/n32 is added so it
can be used by seccomp to explicitely set syscall filters for this ABI.

The patch extends fuse_setattr_in, and extends the flush procedure
(fuse_flush_times()) called on ->write_inode() to send the ctime as well as
mtime.

Allow userspace fs to specify time granularity.

This is needed because with writeback_cache mode the kernel is responsible
for generating mtime and ctime, but if the underlying filesystem doesn't
support nanosecond granularity then the cache will contain a different
value from the one stored on the filesystem resulting in a change of times
after a cache flush.

Make the default granularity 1s.

Pull file locking fixes from Jeff Layton:
 "File locking related bugfixes for v3.15 (pile #2)

   - fix for a long-standing bug in __break_lease that can cause soft
     lockups
   - renaming of file-private locks to "open file description" locks,
     and the command macros to more visually distinct names

  The fix for __break_lease is also in the pile of patches for which
  Bruce sent a pull request, but I assume that your merge procedure will
  handle that correctly.

  For the other patches, I don't like the fact that we need to rename
  this stuff at this late stage, but it should be settled now
  (hopefully)"

* tag 'locks-v3.15-2' of git://git.samba.org/jlayton/linux:
  locks: rename FL_FILE_PVT and IS_FILE_PVT to use "*_OFDLCK" instead
  locks: rename file-private locks to "open file description locks"
  locks: allow __break_lease to sleep even when break_time is 0

Pull input updates from Dmitry Torokhov:
 "The main change is that we now publish "firmware ID" for the serio
  devices to help userspace figure out the kind of touchpads it is
  dealing with: i8042 will export PS/2 port's PNP IDs as firmware IDs.

  You will also get more quirks for Synaptics touchpads in various
  Lenovo laptops, a change to elantech driver to recognize even more
  models, and fixups to wacom and couple other drivers"

File-private locks have been merged into Linux for v3.15, and *now*
people are commenting that the name and macro definitions for the new
file-private locks suck.

...and I can't even disagree. The names and command macros do suck.

We're going to have to live with these for a long time, so it's
important that we be happy with the names before we're stuck with them.
The consensus on the lists so far is that they should be rechristened as
"open file description locks".

The name isn't a big deal for the kernel, but the command macros are not
visually distinct enough from the traditional POSIX lock macros. The
glibc and documentation folks are recommending that we change them to
look like F_OFD_{GETLK|SETLK|SETLKW}. That lessens the chance that a
programmer will typo one of the commands wrong, and also makes it easier
to spot this difference when reading code.

This patch makes the following changes that I think are necessary before
v3.15 ships:

1) rename the command macros to their new names. These end up in the uapi
   headers and so are part of the external-facing API. It turns out that
   glibc doesn't actually use the fcntl.h uapi header, but it's hard to
   be sure that something else won't. Changing it now is safest.

2) make the the /proc/locks output display these as type "OFDLCK"
