Subject: [PATCH wq#for-2.6.38] workqueue: use WQ_MEM_RECLAIM instead of
 WQ_RESCUER

WQ_RESCUER is now an internal flag and should only be used in the
workqueue implementation proper.  Use WQ_MEM_RECLAIM instead.

This doesn't introduce any functional difference.

As this is trivial, I'd like to carry this through the wq tree if
there's no objection.

Thank you.
