New disklabel handling code (Waldi Ravens).
...
These are the final (?) modifications to the layout of the NetBSD/Atari
bootblock. The bootblock handling can be made backwards compatible using
the right config options (COMPAT_11 + DISKLABEL_AHDI).

New interrupt handling code. Highlights:
...
- Interrupt service routines now take a pointer to
the device's softc, rather than a unit number.
- Interrupt handling code in locore.s condensed. Only
remaining "special" handlers are lev0 (spurious),
lev1 (HIL; don't ask), lev6 (clock), and lev7 (NMI).
Only remaining hard-coded device driver reference in
locore is HIL. (clock doesn't count...)
- "dcafastservice" eliminated. DCA driver has new mechanism
to guarantee prompt interrupt service at any ipl (not
just level 5).
- Interrupt code pulled out of autoconf.c and machdep.c and
placed in new file, isr.c

the MI 5380 driver. It has been verified to work on the IIx, IIsi,

- This driver is _not_ intended to be a general purpose replacement
for the `ncrscsi' driver. It is an alternative for those having
problems with that driver.
- Disconnect/reselect doesn't (yet) work, so don't expect SCSI tape
or magneto-optical disk drives to function properly.

- moved disk_busy() call from xdstrategy() to xdc_startbuf()
...
[prevents disk_unbusy panic when disk is loaded (if no
free IOPBs, xdstrategy() would queue the buffer for pickup
by xdcintr() but xdcintr() would never call disk_busy().
xdc_startbuf() is a better place since all bufs are routed
through here] problem detected by girish@dworkin.wustl.edu ,
diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to

Add serial-console support that works with `new-style' (config.new) autconf
...
code. Substantially the same code tested on a 5k/240. Should work on a
5k/1xx. Not tested on a MAXINE, where the single unit may break the
PROM-channel-number to driver-channel-number mapping.

Protect clearing the Intersil chip's interrupt with splhigh(). If this
...
gets interrupted (by the higher priority zs hardware, for example),
the clock can come to a dead stop!

Support kernels configured without an ASC (e.g, 3100-only configs) or
...
without an SII (e.g., TURBOChannel-only configs). Only the same old,
static, set of old-config devices and old pmax rz/tz drivers is
supported.

The prototyping `fixes' broke vmapbuf() and vunmapbuf(), due to a "sz"
...
parameter parameters shadowing locals. Replace vmapbuf() and vunmapbuf()
with the Alpha-port versions, which are cleaner (use round_page(),
trunc_page(), etc.)

to be passed as well as the fp frame.
FPE<->kernel glue code now builds a trapframe structure for passing in
