Pull s390 bugfix from Martin Schwidefsky:
 "One last s390 patch for 4.12

  Revert the re-IPL semantics back to the v4.7 state. It turned out that
  the memory layout may change due to memory hotplug if load-normal is
  used"

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