Hmm. Andrew Morton responded to that initially, but then nothing
happened, and now it's been another six months. Andrew?

The arch/x86/mm/pat.c error handling does seem to be suspect. This is
all code several years old, so none of this is new, and I think Suresh
is gone.  Adding a few other people with recent sign-offs to that
file, in the hope that somebody feels like they own it..
