Pretty nasty hack to make non-exec mappings work.
Instead of using FOE for just emulating references, we also keep track
of a pages executability and don't remove the FOE bit if the page
is not executable.
This is implmented with horrible hacks. Maybe when I have time, I'll
reimplment the whole pmap to allow this without ugly hacks (read: probably
not this decade).
The stack on alpha is now non-exec.
