Just a bunch of work, which would be made on hpcmips/ arena.   When I
was involved with NetBSD porting to one of Vr41xx processor some ago,
I was literally boggled down by the fact of how the port is badly designed.
It could be done smaller, simpler and smarter.  The worst is a dogmatic
use of bus_space, which contribute to nothing.  It'd make no sense to
move to 'shared' arena in that design.
