[git pull] drm radeon + nouveau fixes

[Dave Airlie]

Hi,

so nouveau had a few regression introduced, Ben and Maarten
finally tracked down the one that was causing problems on my
MacBookPro, also nvidia gave some info on the an engine we
were using incorrectly, so disable our use of it, and
one regresion with pci hotplug affecting optimus users.

radeon has an oops fixs, sync fix, and one workaround to
avoid broken functionality on 32-bit x86, this needs
better root causing and a better fix, but the bandaid
is a lot safer at this point.

Dave.
