Inside gtt_restore_mappings() we currently take the obj->resv->lock, but in the future we need to avoid taking this fs-reclaim tainted lock as we need to extend the coverage of the vm->mutex. Take advantage of the single-threaded nature of the early resume phase, and do a single wbinvd() to flush all the GTT objects en masse.
