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 s390 updates for v3.14.

  New features are the perf support for the CPU-Measurement Sample
  Facility and the EP11 support for the crypto cards.  And the normal
  cleanups and bug-fixes"
