thanks, Peter.

The intention was to merge this through the tip tree. Although now I'm
not sure. Options:

        1) take the first patch through the drm-intel tree and apply the
           second patch later
        2) take everything through the drm tree
        3) take everything through the tip tree

What's your preference here?
