Merge branch 'for-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu updates from Tejun Heo: - Nick improved generic implementations of percpu operations which modify the variable and return so that they calculate the physical address only once. - percpu_ref percpu <-> atomic mode switching improvements. The patchset was originally posted about a year ago but fell through the crack. - misc non-critical fixes. * 'for-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: mm/percpu.c: fix potential memory leakage for pcpu_embed_first_chunk() mm/percpu.c: correct max_distance calculation for pcpu_embed_first_chunk() percpu: eliminate two sparse warnings percpu: improve generic percpu modify-return implementation percpu-refcount: init ->confirm_switch member properly percpu_ref: allow operation mode switching operations to be called concurrently percpu_ref: restructure operation mode switching percpu_ref: unify staggered atomic switching wait behavior percpu_ref: reorganize __percpu_ref_switch_to_atomic() and relocate percpu_ref_switch_to_atomic() percpu_ref: remove unnecessary RCU grace period for staggered atomic switching confirmation
