[git pull] mm + drm vmwgfx coherent

[Dave Airlie]

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.

Thanks, pulled (and the delay wasn't because of me being nervous about
the code, it was just because of turkey and a day of rest afterwards).

And I appreciate the separation - not because I wasn't comfortable
with the final code, but simply because it's a rather different thing
than the usual drm code. Having that as a separate pull and not mixed
up with the regular driver updates is just how I prefer it.

Thanks,

              Linus
