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()
