Git Kernel HEAD 07961ac7c0ee8b546658717034fe692fd12eefa9 vs patched diff

Rodrigo, I believe you are right. It was very late yesterday when I wrote the
last comment :-(

There could be more differences, because my initial (#60) test was with kernel
3.9.0-rc5 from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc5-raring/ and the
(partially) patched one is from HEAD 07961ac7c0ee8b546658717034fe692fd12eefa9
kernel branch 'master' of
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux (I am using it
right now, with glxsgears running, and no bug symptoms).

Your patch was applied partially, because it was older than the kernel I
applied it to. I attach the diff file here, in case you would like to check
what was really applied. I would also like to revert it and try the original
kernel as it is, just to check.

In your last comment, you refer to a certain patch. I suppose it is from the
http://cgit.freedesktop.org/~danvet/drm-intel/commit/?h=drm-intel-nightly
branch, isn't it?
