Merge branch 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull a percpu fix from Tejun Heo: "Fix for a percpu allocator bug where it could try to kfree() a memory region allocated using vmalloc(). The bug has been there for years now and is unlikely to have ever triggered given the size of struct pcpu_chunk. It's still theoretically possible and the fix is simple and safe enough, so the patch is marked with -stable" * 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: make pcpu_alloc_chunk() use pcpu_mem_free() instead of kfree()
