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

Pull s390 fixes from Martin Schwidefsky:
 "Two bug fixes

   - a memory alignment fix in the s390 only hypfs code

   - a fix for the generic percpu code that caused ftrace to break on
     s390. This is not relevant for x86 but for all architectures that
     use the generic percpu code"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  percpu: use notrace variant of preempt_disable/preempt_enable
  s390/hypfs: Use get_free_page() instead of kmalloc to ensure page alignment
