0fb6b9a8f8 Rework the interrupt code, shaving some cycles off in the process.
Rather than an "iointr" routine that decomposes a vector into an
IRQ, we maintain a vector table directly, hooking up each "iointr"
routine at the correct vector.  This also allows us to hook device
interrupts up to specific vectors (c.f. Jensen).

We can shave even more cycles off, here, and I will, but it requires
some changes to the alpha_shared_intr stuff.

b0ce38fd8a Switch to the new `evcnt' mechanism for counting interrupts. Maintain
a per-CPU interrupt counter for clock, device, and interprocessor
interrupts.

cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).

ae55376f19 - Remove unused bt459reg.h.
- sfbvar.h has gone, placing patch on holes for now.  Every TC framebuffer
  has a single explosure of xxfb_cnattach() which could be bridged by MI
  land.

31a77e61b3 Leave out display console related bits if wscons is not compiled in.
Should fix link error reported by Kevin <kev@drule.org>.

ab9470909c Preliminary support for both serial consoles and kbd/display wscons
consoles for TC alphas.  Based on code from Takuya Koumoto
<takuya-k@is.aist-nara.ac.jp> as well as some parts of Toru Nishimura's
and Matthias Drochner's work on pmax wscons.  This relies on the
NEW_SCC_DRIVER.

693b3e7262 Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.

90789b53dd by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory.  (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)

70147216ec Include a PMAGB-BA in the list of built-in devices only if SV_GRAPHICS
is set in the RPB's rpb_variation field.  This fixes a bug where machines
(e.g. the 3000/900) would see that they could touch memory where a built-in
PMAGB-BA, assume that it was there, and panic later because the memory they
were accessing didn't look like PMAGB-BA registers (because it wasn't).

2d03e599c7 don't depend on being able to read the IMR. Apparently, it doesn't
work (as documented in the DEC 3000/[3-9]00 System Programmer's Manual)
in some of the older 3000/500 systems.

7c1754fdff add a bit of clarafication in a comment, and change the interrupt
handling code so that if a given interrupt is disabled (and therefore
can't have caused the actual I/O interrupt), its handler won't be
called even if its bit is set in the interrupt register.

85854cb4ad preliminary Alpha support. note that NOT ALL OF THE MODIFICATIONS TO

_incredibly_ hack-ish, etc., but it works.
