Subject[2.6.20.16 review 04/28] make freezeable workqueues singlethread
It is a known fact that freezeable multithreaded workqueues doesn't like
CPU_DEAD. We keep them only for the incoming CPU-hotplug rework.

Sadly, we can't just kill create_freezeable_workqueue() right now, make
them singlethread.
