Merge branch 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq

Pull workqueue updates from Tejun Heo:
 "Most of the changes are around implementing and fixing fallouts from
  sysfs and internal interface to limit the CPUs available to all
  unbound workqueues to help isolating CPUs.  It needs more work as
  ordered workqueues can roam unrestricted but still is a significant
  improvement"
