[3/3] drm/i915: eliminate vm->insert_entries()

Commit Message

Ben Widawsky July 13, 2013, 4:45 a.m. UTC

With bind/unbind function pointers in place, we no longer need
insert_entries. We could, and want, to remove clear_range, however it's
not totally easy at this point. Since it's used in a couple of place
still that don't only deal in objects: setup, ppgtt init, and restore
gtt mappings.
