I'm suspecting that this one might also have been fixed unknowingly by one of the other commits (this is backed by the fact that I haven't been able to reproduce _any_ cpu-hotplug-related failure as of the latest mainline kernel), on the other hand I don't know exactly why. I guess I should run a longer test to see if this comes up again. (Oh, maybe it was an RCU-type thing? Nick Piggin recently had a patch that fixed some RCU error. Peter?)
