Pull s390 fixes from Martin Schwidefsky:
 "A couple of bug fixes, the most hairy on is the flush_tlb_kernel_range
  fix.  Another case of "how could this ever have worked?"."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/kdump: Do not add standby memory for kdump
  drivers/i2c: remove !S390 dependency, add missing GENERIC_HARDIRQS dependencies
  s390/scm: process availability
  s390/scm_blk: suspend writes
  s390/scm_drv: extend notify callback
  s390/scm_blk: fix request number accounting
  s390/mm: fix flush_tlb_kernel_range()
  s390/mm: fix vmemmap size calculation
  s390: critical section cleanup vs. machine checks
