Merge branch 'for-4.7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu fixes from Tejun Heo: "While adding GFP_ATOMIC support to the percpu allocator, the synchronization for the fast-path which doesn't require external allocations was separated into pcpu_lock. Unfortunately, it incorrectly decoupled async paths and percpu chunks could get destroyed while still being operated on. This contains two patches to fix the bug" * 'for-4.7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: fix synchronization between synchronous map extension and chunk destruction percpu: fix synchronization between chunk->map_extend_work and chunk destruction
