Hmm. Seems dangerous to rely on this, because functions could change
from inline to out of line without people noticing that it affects this
very corner case for kprobes + paravirt + stop_machine. Is there a way
to cascade the __kprobes declaration to all called functions, perhaps
with a static checker, like sparse?
