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

Pull s390 patches from Martin Schwidefsky:
 "The biggest patch is the rework of the smp code, something I wanted to
  do for some time.  There are some patches for our various dump methods
  and one new thing: z/VM LGR detection.  LGR stands for linux-guest-
  relocation and is the guest migration feature of z/VM.  For debugging
  purposes we keep a log of the systems where a specific guest has lived."

Fix up trivial conflict in arch/s390/kernel/smp.c due to the scheduler
cleanup having removed some code next to removed s390 code.

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

  [S390] stack dump: fix indentation in output
  [S390] kernel: Add OS info memory interface
  [S390] Use block_sigmask()
  [S390] kernel: Add z/VM LGR detection
  [S390] irq: external interrupt code passing
  [S390] irq: set __ARCH_IRQ_EXIT_IRQS_DISABLED
  [S390] zfcpdump: Implement async sdias event processing
  [S390] Use copy_to_absolute_zero() instead of "stura/sturg"
  [S390] rework idle code
  [S390] rework smp code
  [S390] rename lowcore field
  [S390] Fix gcc 4.6.0 compile warning
