So I guess I am saying don't follow the example of the
m68knommu, which currently doesn't do this :-)

When support for MMUless ARM cores hits the 2.6 mailine
it will be in the arm architecture branch, not an armnommu.
Longer term we want to merge the m68knommu as well, though
there is a little work to do for that.

The SH support is a good example, seemless MMU and non-MMU.

Greg
