Subject[git pull] mm + drm vmwgfx coherent
Hi Linus,

This is just a separated pull for the mm pagewalking + drm/vmwgfx work
Thomas did and you were involved in, I've left it separate in case you
don't feel as comfortable with it as the other stuff.

It has mm acks/r-b in the right places from what I can see.

Dave.
