Hmm, change it to work with longs only but also make it work without
casts? You mean then change all places where bitops are applied to
exclusively use 'unsigned long' as the fundamental type? I didn't look
at the number of places that would require changing, but I'm afraid it'd
be quite a few (and it might get you further away from Linux originals
in some cases).
