Some, like the crusty AGP gart or boot time mem_encrypt usage is fine, the former nobody cares about, the latter is not interresting because boot-time. But others like the drm_cache usage is utter nonense and should really be replaced like we already do in cpa_flush_array() for PREEMPT, and this should really be made unconditional.
