How about:
CPU_DEAD does nothing. After __cpu_disable() cwq->thread runs on all CPUs and becomes idle when it flushes cwq->worklist: nobody will add work_struct on that list.
CPU_UP: if (!cwq->thread) create_workqueue_thread(); else set_cpus_allowed(newcpu);
flush_workqueue: for_each_possible_cpu() // NOT online! if (cwq->thread) flush_cpu_workqueue()
Oleg.
