No, its the same accessors for both, since the need to distinguish them hasn't really come up. Could you put a "if (preemptable()) return;" guard in your implementations?
That would be a band-aid but would probably do the trick for now for !-rt, tho it wouldn't do the right thing for -rt...
Otherwise I have no objections to passing the mm in (we'll probably just continue to ignore the arg in x86-land).
