8472af018d Update a kludge from 4.4bsd/pmax: DECstation PROMs force the clock to 
be in 1972 or 1973. If the clock is set to the actual time, the PROM
appears to reset the chip date to 1972 at each reboot.

Change the "year offset" from 22 years to 24 years (good till 1997)
until this code is replaced with something that uses the chip as a
seconds-since-beginning-of-year clock (encoded as a date, relative to
1972-01-01 00:00:00).

d9bce7422e Move the obviously machine-dependent HP-UX compat code to hpux_machdep.{c,h}. 
A fair bit of this, the m68k core dump and exec goo, can probably be
made into a generic m68k hpux module, eventually.

More to be placed in hpux_machdep.c - keep your eyes peeled...

36817f8d02 Rewrite (a copy of) the emul-sunos termio/termios emulation code to 
emulate Ultrix termio/termios instead. Ultrix termio c_cc has separate
VMIM/VTIME attributes, and the Ultrix termios c_cc is a strict
superset of Ultrix termio c_cc. The termios-only c_cc indices are
all changed, relative to SunOS.

6d6c652f18 New driver for the Sun SCSI-3 VME and 4/100-series SCSI "Weird" controllers, 
utilizing David Jones' new MI NCR 5380 code.  Ported from the sun3 ncr_si.c
and "sw" DMA code written by me.

This driver contains user-configurable "options", which can be set via the
"flags" directive in the kernel configuration file.  By default, only
DMA is enabled.  DMA completion interrupts and reselection may be enabled
by setting the appropriate bits with "flags".  See si.c for details.

Note that DMA completion interrupts and reselection don't yet work on the
4/100 controller.  I don't know why, and it's unlikely that I'll have
the opportunity to find out any time soon.  DMA does work, and results
in a considerable performance increase.

DMA, DMA completion interrupts, and reslection all work on my 4/260 (VME)
system with modern SCSI-II disks.

3319ad7b61 XXX TEMPORARY STOP-GAP MEASURE! A 12-bit command modifier was being 
squished into an 8-bit position in a command stream!  Which one is wrong?
Changed the constant from 0x140 to 0x40, which is what ended up happening
anyhow.  This exists in the old Utah sources, too!  How long has this
bug existed?!
