	syssrc/sys/arch/sun2/sun2: machdep.c

Log Message:
Much bus_dma work.  When destroying a map, unload it if it's
loaded.  Added more comments.  Fixed the perspective of a 24-bit
device from the original sun4 code to match the sun2.  For now,
we don't double-map pages into DVMA space by hand, we're back
to using pmap_enter.  Be more paranoid about saving and
restoring the MMU user context.
