Pull CIFS fixes from Steve French:

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: don't instantiate new dentries in readdir for inodes that need to be revalidated immediately
  cifs: set sb->s_d_op before calling d_make_root()

  Do not attempt to do cifs operations reading symlinks with SMB2
  cifs: extend the buffer length enought for sprintf() using

Pull more ext4 bugfixes from Ted Ts'o:
 "A number of miscellaneous ext4 bugs fixes for v3.11, including a fix
  so that if ext4 is built as a module, to allow it to be unloaded"

* tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
  ext4: flush the extent status cache during EXT4_IOC_SWAP_BOOT
  ext4: fix mount/remount error messages for incompatible mount options
  ext4: allow the mount options nodelalloc and data=journal

Pull w/w mutex deadlock injection fix from Ingo Molnar.

This bug made the CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y option largely
useless, but wouldn't affect normal users.

* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  mutex: Fix w/w mutex deadlock injection

Previously we weren't swapping only some of the extent_status LRU
fields during the processing of the EXT4_IOC_SWAP_BOOT ioctl.  The
much safer thing to do is to just completely flush the extent status
tree when doing the swap.

  caused tons of USB devices (and one RAID card) to cease to function
  and a megaraid_sas firmware initialisation problem which causes kdump
  failures"

Pull powerpc fixes from Ben Herrenschmidt:
 "This includes small series from Michael Neuling to fix a couple of
  nasty remaining problems with the new Power8 support, also targeted at
  stable 3.10, without which some new userspace accessible registers
  aren't properly context switched, and in some case, can be clobbered
  by the user of transactional memory.

  Along with that, a few slightly more minor things, such as a missing
  Kconfig option to enable handling of denorm exceptions when not
  running under a hypervisor (or userspace will randomly crash when
  hitting denorms with the vector unit), some nasty bugs in the new
  pstore oops code, and other simple bug fixes worth having in now.

  Note: I picked up the two powerpc KVM fixes as Alex Graf asked me to
  handle KVM bits while he is on vacation.  However I'll let him decide
  whether they should go to -stable or not when he is back"
