f134e05316 Fixed performance problems caused by the ring buffer becoming flodded when 
multiple packets were being received due to not flushing newly received

ab3b20faba Remove the compile-time conditionalization for either CFB or SFB, 
based on "#ifdef MELLON":  examine the framebuffer dimensions in the
fb softc, and initialize the x-axis offset appropriately.

User-level changes to (e.g.) an Xserver are still needed to work
on an SFB.

94ca9f6aa0 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

d6f4511690 All interrupt routines (except the HIL; don't ask) now take a pointer 
to a softc, rather than a unit number.  Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.

YAY!  No more need for dcafastservice!

HIL: squish instances of "(void) splhil()" and "(void) spl0();".

a5c3ac2538 Allocate a single static colourmap array for aglass-tty consle 
framebuffer and malloc() all others.  Remove old-config unit-number checks.

This driver no longer requires the "needs_count" flag.

1c03bcb897 Finish converting MAXINE dtop driver to use new-style config. 
The dtop driver no longer requires the "needs-count" flag.

Fix a panic in boot-time interrupt establish. The "generic" pmax
interrupt-establish  code assumes that all interrupt args are new-config
device structs accessed via  a struct cfdriver.   Make it so.
