Is it possible that this may fix the "bad pte" panic with "TPTE at
0xffff8000040028c8  IS ZERO @ VA 800519000" that I saw at
http://docs.FreeBSD.org/cgi/mid.cgi?1148482556.35287.18.camel ?

I've only ever seen that panic once, so I can't really test this commit
to see if it does indeed fix that issue.

Thanks,

Gavin
