Ah, I had a quick look through your v2 because I got a link into it from
Ingo but didn't find it. I'll have to ask Google to locate this v1. I
suppose that's what's wrong with my last patch. It directly does a call
preempt_schedule -- which I had hoped would work due to its asmlinkage,
but apparently there's more to it.

Also, I suppose there's a few volatile thingies missing.
