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

Pull s390 patches from Martin Schwidefsky:
 "Some more bug fixes and a config change.

  The signal bug is nasty, if the clock_gettime vdso function is
  interrupted by a signal while in access-register-mode we end up with
  an endless signal loop until the signal stack is full.  The config
  change is for aligned struct pages, gives us 8% improvement with
  hackbench."
