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"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (23 commits)
  s390/smp: wait until secondaries are active & online
  s390/hibernate: fix save and restore of kernel text section
  s390/cacheinfo: add missing facility check
  s390/syscalls: simplify syscall_get_arch()
  s390/irq: enforce correct irqclass_sub_desc array size
  s390: remove "64" suffix from mem64.S and swsusp_asm64.S
  s390/ipl: cleanup macro usage
  s390/ipl: cleanup shutdown_action attributes
  s390/ipl: cleanup bin attr usage
  s390/uprobes: fix address space annotation
  s390: add missing arch_release_task_struct() declaration
  s390: make couple of functions and variables static
  s390/maccess: improve s390_kernel_write()
  s390/maccess: remove potentially broken probe_kernel_write()
  s390/watchdog: support for KVM hypervisors and delete pr_info messages
  s390/watchdog: enable KEEPALIVE for /dev/watchdog
  s390/dasd: remove setting of scheduler from driver
  s390/traps: panic() instead of die() on translation exception
  s390: remove test_facility(2) (== z/Architecture mode active) checks
  s390/cmpxchg: simplify cmpxchg_double
