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

Pull s390 updates from Martin Schwidefsky:
 "The major change in this merge is the removal of the support for
  31-bit kernels.  Naturally 31-bit user space will continue to work via
  the compat layer.

  And then some cleanup, some improvements and bug fixes"
