I'd been wanting to do this for ages, but Jake implemented it on the
sparc64 a while ago now and he kinda shamed me into doing it. :-)

The main difference is that sparc64 doesn't have to go to the trouble of
intercepting the pmap_release() since the VM hardware is different and it
doesn't have to worry about a potentially borrowed page directory getting
bzero()'ed.

Cheers,
-Peter
