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.
