Yeah. With everything else being converted to ggtt, I liked naming the
node ggtt. As for the offset, I used that to find all the places that
needing fixing up, and then decided not to change it back since I killed
it in a future patch anyway.
If you want to fix it up on merge, I am fine with that - though I guess
after the fact, I do prefer ggtt.
