 Ugh, this should be a separate set of functions selected at the run time. 
It should be fairly trivial to rewrite it this way (best done with
processor-specific functions expanded from common templates for ease of
maintenance), but the size of the resulting interrupt masking window is
unacceptable.  A more finegrained implementation is really desireable,
with an interrupt enable window every page or so, but your proposal should
be fair enough for the sake of usability once rewritten as I suggested.
