trees for secondary powerdown

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...

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.
