So, I resetted next-20130726 to the merge-commit of
drm-intel/for-linux-next, which is as expected bad.

First, I looked w/ a Grrr at i915_gem_stolen.c with a focus on
"drm/i915: Use Graphics Base of Stolen Memory on all gen3+", but this
commit is also in next-20130725.

Yeah, might be the stuff comes from the merge including vma stuff.
