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.
