Greg, et al,
Yesterday we found a bug in this patch. The patch still fixes
the original problem, but we introduced an error in certain
page_mkwrite() corner cases. We have one more validation test and then
I'm sending the fix to Linus.
So we really want both this commit and the followup fix in
-stable. You'll be CC'd when I send Linus the pull request.

Joel
