trees for secondary powerdown

[Dave Airlie]

Hi Takashi,

I've put two branches in my repo,

http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-optimus-power-down
http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-optimus-power-down-snd-merge

git://people.freedesktop.org/~airlied/linux is the tree.

The second tree is just the vga switcheroo and sound patch, I've
changed one line from the
previous posted patch to reinstate the irq handler check for runtime
pm, but only for cards
with the runtime pm flag.

Can you see if this merges into your tree okay? if so we can both
merge that branch to
our trees and I'll build on top of it.

Dave.
