[PATCH] for 2.6.22, make freezeable workqueues singlethread

[Oleg Nesterov]

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.
