I think I suggested doing this patch as an intermediate step to
get rid of the macros first, so we don't get any new users.
I agree that we should also remove the static mappings eventually,
and once we do that, the machine descriptors can be unified again.

I have not checked which of the map_desc entries are currently used
at all, or what it would take to remove them.
