"Don't pollute common entry file with MMU versions specific bits (as new
MMU doesn't have PID register)"
However Jose thankfully pointed me (off list) that this patch is broken

Any Machine check disables MMU but we now we only re-enable for TLB
faults related MC, so this will have to be redone.
Thx,
