This sort of merging is fairly easy to do incrementally, at least by
someone that has both platforms available. An easy first step would be to
move the m68knommu stuff that are implemented differently over as _nommu
files, similar to how the _32/_64 renames happened, and then set about
converging the two little by little. This is what I've been doing with
sh64->sh integration for example, despite fundamental differences like
having a totally different register layout and instruction set.
