[Intel-gfx] [PATCH 0/1] drm/i915: Another version of the vga stop_machine monstrosity

[ville.syrjala at linux.intel.com]

Here's a slightly improved version of the VGA stop_machine() patch.

The main new thing is switching ctg/elk over to port IO. That appears to have
cured the hangs from Chris's lid_notify riddled ctg machine.

What I'd really like is some kind of tested-by note from Alex Williamson to
make sure I didn't accidentally break something important. Well, assuming people
are willing to overlook the uglyness to slip this in at all.
