Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Martin Schwidefsky:
 "The bulk of the patches for the 3.13 merge window.

  Heiko spent quite a bit of work to improve the code generation for the
  kernel.  That includes the exploitation of the interlocked-access
  facility for the atomics and bitops implementation and the improvement
  for the -march and -mtune compiler settings.

  Another important change is the removal of the user_mode=home option,
  user processes now always run in primary space.  The storage keys are
  not initialized at system startup any more, with that the storage key
  removal work is complete.  For the PCI support the hibernation hooks
  have been implemented.

  And as usual cleanup and fixes"
