[REGRESSION] nouveau: Severe screen corruption on (0xaf, nv50)

From: Henrik Rydberg

Hi Ben,

3.7-rc1 messed up the screen on my MacBookAir3,1 (nv50, 0xaf) pretty
badly. Not surprisingly,

commit 3863c9bc887e9638a9d905d55f6038641ece78d6
Author: Ben Skeggs <bskeggs@xxxxxxxxxx>
Date: Sat Jul 14 19:09:17 2012 +1000

drm/nouveau/instmem: completely new implementation, as a subdev module

is the first bad commit. Standing on that commit, booting and then
starting X yields the output below. Hints are especially appreciated,
considering the patch is almost 8000 lines.

Thanks,
Henrik
