Changing the semantics of PF_THREAD_BOUND without so much as
a comment in your changelog or buy-in from the scheduler
maintainers is a big no-no.
In fact I've already said a number of times this patch isn't going
anywhere.
Which is probably fine, because I see no reason why Andrea's
numa threads would need PF_THREAD_BOUND in the first place.
