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.

a PTE in whatever user context happened to be set on
entry.

and only splnet() is allowed for the protection of data structures

In prom_init, when making our local copy of the bootparams,

be sure to calculate the shift in terms of chars, not struct
bootparams, and don't shift undefined arguments.

Fixed has_context to return true on the kernel pmap,

which always has context zero. This was causing panics
under DIAGNOSTIC.

The mainbus doesn't define a device name in the attach args
...
after attaching the special busses, so just match when it
isn't, instead of calling strcmp with it.
