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
