If we know that user address space has never executed on other cpus
we could use tlbiel.

Now checking against flush_hash_page, I am wondering whether I need to handle
transcational memory in case of tlbiel ? Michael, can you let me know if
this is needed ?

Also, beware that we have code that sets "tlbiel" in the page definition
array to 0 on all but 4k and 64k pages...

Cheers,
Ben.
