[1/2] drm/i915: move functions around

Commit Message

Daniel Vetter Aug. 20, 2012, 9 a.m. UTC

Prep work to make Chris Wilson's unbound tracking patch a bit easier
to read. Alas, I'd have preferred that moving the page allocation
retry loop from bind to get_pages would have been a separate patch,
too. But that looks like real work ;-)
