Merge branch 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git into for-3.16
Pull percpu/for-3.15-fixes into percpu/for-3.16 to receive
0c36b390a546 ("percpu-refcount: fix usage of this_cpu_ops").
The merge doesn't produce any conflict but the automatic merge is
still incorrect because 4fb6e25049cb ("percpu-refcount: implement
percpu_ref_tryget()") added another use of __this_cpu_inc() which
should also be converted to this_cpu_ince().
This commit pulls in percpu/for-3.15-fixes and converts the newly
added __this_cpu_inc() to this_cpu_inc().
