Merge branch 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu updates from Tejun Heo: "Nothing interesting. A patch to convert the remaining __get_cpu_var() users, another to fix non-critical off-by-one in an assertion and a cosmetic conversion to lockless_dereference() in percpu-ref. The back-merge from mainline is to receive lockless_dereference()" * 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: Replace smp_read_barrier_depends() with lockless_dereference() percpu: Convert remaining __get_cpu_var uses in 3.18-rcX percpu: off by one in BUG_ON()
