Looking at the pmap code real quick, I think the original authors assumed quick kernel entries were not shared. Since they can be, we should have to add pv_entrys and the cache vac/fix process on the pmap_kenter_internal called routines too. I am still thinking the ARM code should revolve to FreeBSD style (recursive page tables, make SMP ready, etc). --Mark.
