[PATCH 0/3] LP#1158689 -- nouveau screen corruption

[Andy Whitcroft]

We have reports of screen corruption under nouveau.  This seems to be
triggered by enabling bits of h/w we do not actually have.  Following this
email are three patches (all cherry-picks) which pull in support for enabling
only the present h/w.  This does all of this for a raft of Nvidia hardware.

This has been tested to fix the issue on one specific device, but does
"fix" a number more.  It is also rather invasive, though as I said they
are all cherry-picks.  Please consider for SRU to trusty, but I would
suggest it needs to go through a full SRU cycle after release.

Please consider for SRU to trusty.

  drm/nouveau/devinit: tidy up the subdev class definition

  drm/nouveau/device: provide a way for devinit to mark engines as
    disabled
  drm/nv50-/devinit: prevent use of engines marked as disabled by
    hw/vbios
