_that_ is the root of all ugly in that thing. I still find it utterly insane you can create 'per-cpu' workqueues and then violate the per-cpu property with hotplug and get your work ran on a different CPU.
It should be a hard error to use queue_work_on() and then run the work on a different cpu. Yet somehow this isn't so.
