Honestly I just forgot the permissions code was in -next (and has been
since before 2.6.32 opened now that I think about it).  I remembered to
drop that stuff for my 2.6.32 pull request (which came in WAY to late
for you to care about) but forgot I needed to pull it back out this
time.  It will be dropped (even though I think it's good to go, limiting
what I'm trying to get Al/hch to look at is my only hope)

No question this was my stupidity.  When I was rebasing my stuff on top
of your tree to make sure it would merge nicely before I ask for a pull
this patch had conflicts.  While resolving the conflict I added the -W
to the Makefile to make sure that I didn't screw up the point of the
patch.  I knew the warnings were going to pop out and I just ignored
them.  I guess I managed to save the Makefile by accident.  Obviously
I'm going to fix that patch to what it's been in -next (where sfr has
been handling the conflict)

/me sets the clock for one week for next pull request.
