Merge branch 'for-3.17-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq

Pull workqueue fix from Tejun Heo:
 "create_singlethread_workqueue() is the old interface which is kept
  around for backward compatibility - each should be reviewed to
  determine whether singlethread usage was to save worker threads or for
  ordering guarantee and whether it's depended upon by memory reclaim
  path.

  While adding NUMA support for unbound workqueues during v3.10, I
  forgot to update it breaking the singlethread and ordering properties
  on NUMA setups.  The breakage was unfortunately rather subtle and went
  without being reported until now.

  The only missing piece is __WQ_ORDERED flag which makes the unbounded
  workqueue use a single backend queue across different NUMA nodes.
  It's fixed by making create_singlethread_workqueue() wrap
  alloc_ordered_workqueue() so that possible future updates are
  inherited automatically"
