Yay! :-)

Well, to be more precise, this is for mbuf clusters...  (the mb_map change
at least :-)

but since you now have a PMAP_MAP_POOLPAGE(), you get ALL of the cool
benefits of the direct-mapped pool pages... including DRASTICALLY
reduced kmem_map usage!

This is cool... I didn't realize the VAX port direct-mapped all of
physical RAM :-)
