d0742ed3c5 Several things: 
1) If we get an unexpected disconnect, issue a REQUEST SENSE, as recommended
by the SCSI-2 spec.  If the target created a contingent allegiance condition,
this will clear it.  Also, if it happened while sending a SDTR or WDTR message,
disable negotiation for that target.
2) Since some lame devices still don't deal correctly, make sure we deassert
ATN if our last message out is interrupted.  If we get a MESSAGE PARITY ERROR,
we'll reassert ATN anyway.  This should ensure that we never have to send a
MESSAGE NO OPERATION.
3) Set AIC_ABORTING only when actually sending a BUS DEVICE RESET or ABORT,
so we get better error detection.
4) Other internal reorganization of no consequence.

5f20924433 Move the I/O map kludge for II-class machines into the MRG init code. No 
effective change, but this is more correct and averts some potential
problems.

cf4009e56c Include support for sun4m timers and counters: hardware register layout

pk
8de1fd22bc Add sun4m support. Many, many changes.. 
Note on multi-architecture kernels: most architecture dependent traps are
forked off directly by having a separate trap table for each (sun4,sun4c,sun4m)
This reduces the number of tests on `cputyp' significantly, and it's easier
on the mind. There are still some entry points that need to test `cputyp',
most notably microtime().. yuck.

macros (see machine/param.h) wherever possible.
