drm/i915: track objects in the gtt
This is required to restore gtt mappings on resume when agp is gone. The right way to do this would be to make sturct drm_mm_node embeddable and use the allocation list maintained by the drm memory manager. But that's a bigger project. Getting rid of the per bo agp_mem will save more memory than this wastes, anyway. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
