I don't know how much is shared between, say, luna68k and luna88k--I
know not much is shared between sun3 and sparc or mac68k and macppc,
but some is (arguably, adb should be in dev/adb, though)...  I tend
to think that the most reasonable arrangements don't try to nest cpu
and machine architectures, so I think that

	cpu/mips and machine/pmax,
	arch/mips and machine/pmax, or
	cpu/mips and arch/pmax

make the most sense.  The first makes the most sense to me, and the
last requires probably the least change for most people's navigational
