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

Pull s390 updates from Martin Schwidefsky:
 "Pretty boring for a merge window pull.

  One change in behaviour is the patch for dasd driver, the module which
  provides the diagnose discipline is now loaded automatically.

  The SCLP code got a nice cleanup, a new global structure replaces a
  bunch of accessor functions.

  And a couple of random, small improvements"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/pci: improve handling of hotplug event 0x301
  s390/setup: fix DMA_API_DEBUG warnings
  s390/zcrypt: remove obsolete __constant
  s390/keyboard: avoid off-by-one when using strnlen_user()
  s390/sclp: pass timeout as HZ independent value
  s390/mm: s/specifiation/specification/, s/an specification/a specification/
  s390/sclp: Use DECLARE_BITMAP
  s390/dasd: Enable automatic loading of dasd_diag_mod
  s390/sclp: move sclp_facilities into "struct sclp"
  s390/sclp: get rid of sclp_get_mtid() and sclp_get_mtid_max()
  s390/sclp: unify basic sclp access by exposing "struct sclp"
  s390/sclp: prepare smp_fill_possible_mask for global "struct sclp"
