Robert Noland 4cd2e9581f resync to git master 
This reverts a private patch which is causing issues with many Intel chipsets.
I will review that patch and see what we need to do to fix it up later, but
for the time being, we will just get these chips working again.

This update contains a lot of code cleanup and is post gem merge
(no, we don't have gem support).  It should prove much easier to read the
code now.  A lot of thanks goes to vehemens for that work.  I have adapted
the code to use cdevpriv for tracking per open file data.  That alleviates
the old ugly hack that we used to try and accomplish the task and helped to
clean up the open / close behavior a good bit.  This also replaces the hack
that was put in place a year or so ago to prevent radeons from locking up
with AIGLX enabled.  I have had a couple of radeon testers report that it
still works as expected, though I no longer have radeon hardware to test with
myself.  Other various fixes from the linux crew and Intel, many of
which are muddled in with the gem merge.
