Overall performance degregation is embrassing these days.  My plan
under desk is, 1) /sys/dev/rasops/ console screen rendering should be
revisited.  Partial word load/store brings read-modify-write memory
traffic.  That hurts speeds visibly.  2) TLB miss handler should be
retooled.  Indeed, pmap.c will be replaced with the new one.
