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

Pull s390 updates from Martin Schwidefsky:
 "An optimization for irq-restore, the SSM instruction is quite a bit
  slower than an if-statement and a STOSM.

  The copy_file_range system all is added.

  Cleanup for PCI and CIO.

  And a couple of bug fixes"
