I may be splitting hair but shouldn't this patch be moved
earlier?patch1/3-4 seem to be completely tied with the introduction and
use of the fixup_controls() callback, I am not sure I see the link with
the IRQ stuff. Or conversely move this last if this makes more sense.
Also while I am at it, I wouldn't hurt to have an explanation of the
races conditions earlier, it's only in patch3 that the race condition is
described in details.
