drm: move read_domains and write_domain into i915
i915 is the only driver using those fields in the drm_gem_object structure, so they only waste memory for all other drivers. Move the fields into drm_i915_gem_object instead and patch the i915 code with the following sed commands: sed -i "s/obj->base.read_domains/obj->read_domains/g" drivers/gpu/drm/i915/*.c drivers/gpu/drm/i915/*/*.c sed -i "s/obj->base.write_domain/obj->write_domain/g" drivers/gpu/drm/i915/*.c drivers/gpu/drm/i915/*/*.c Change is only compile tested. v2: move fields around as suggested by Chris.
