"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 
(based on some internal emails).
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,
