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
