(requested by jym in ticket #372).
Enable the map/unmap recursive mapping functions for all Xen ports for
For an unknown reason (to me) Xen refuses to update VM translations
when the entry is pointing back to itself (which is precisely
what our recursive VM model does). So enable the functions that take
care of this, which will avoid all sort of memory corruption upon restore
leading domU to trample upon itself.
Save/restore works again for amd64. The occasional domU frontend
still present, but is harmless to dom0. Now we have a working shell and
ddb inside domU, that helps debugging a tiny bit.
