Ingo dropped it on Saturday because it makes locking_selftest() unhappy.

That is because we call locking_selftest() way before we're ready to
call schedule() and guess what it does :-/

I'm not entirely sure what to do.. ideally I'd shoot locking_selftest in
the head, but clearly that's not entirely desired either.
