Ahh. Ok. Different case from the one I thought you were worried about. And yeah, I guess that one does require us to mess with the low-level asm code (although I do wonder if we could not make the whole do_notify_resume + reschedule code be generic C code - it's a lot of duplicated subtle asm as it is).
