[Call for testers] DRM device-independent code update to Linux 3.8 (take #2)

Here is a new patch to based on HEAD r279508:

You can apply it to a Subversion checkout using the following command:
    svn patch drm-update-38.i.patch

There are few changes:
    o  The panic reported by J.R. Oldroyd is fixed, but not the CP init
    o  A lock assert was added, suggested by Konstantin Belousov

I had several panics ("Stray timeout") with a taskqueue used by TTM, but
it didn't occur in the past 6 days. Maybe it was a problem outside of DRM.

I would like people to test again and report :) If something fails,
please post a full dmesg, taken after loading the relevant *kms module,
or the core.txt.$N file if it's a panic.

Hans Petter and Ed, I couldn't reproduce neither of your problems (HDMI
hotplug events storm and VT-switch misbehaviour). However, they both
involve callouts, like the "Stray timeout" panic I had with TTM. I
suspect there was a transient problem with callouts in HEAD at the same
time. Could you please test again with this patch and a very recent HEAD?

Thank you to everyone!
