The difference is admittedly very subtle (though probably
not to some Linux kernel developer purists).  The question
is whether xen is subsidiary architecture (which uses
the mach- prefix) or whether it is functionality that can
be turned on or off (no mach- prefix).

And since this will appear hard-coded in include lines
in source files, we do need to decide one way or the
other.
