Should this be defined by a shared header?

i was going to poke that next, but i don't think fixing the few fringe arches 
should be predicated on cleaning up a mess that has been here for over a decade.

How dare you call the PA a fringe architecture, it's only been dead for 
a decade or so.

If you're going to poke at factoring that code out next, then I don't 
mind going forward now.  All these are approved.
