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

Pull s390 fixes from Martin Schwidefsky:
 "Two small bug fixes and a follow-up to the CONFIG_NR_CPUS change.

  A kernel compiled with CONFIG_NR_CPUS=256 will waste quite a bit of
  memory for the per-cpu arrays.  Under z/VM the maximum number of CPUs
  is 64, the code now limits the possible cpu mask to 64 if running
  under z/VM"
