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.

8bf44847a8 Fix DEC3000/300 TC slot numbering. There is an address space hole 
between two TC option cards and 3 builtin TC devices.  Was uncovered by
mrg's change made at Nov 1999 and pointed by tsutsui.

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.)

cb0eb158e7 fix the test for option slot interrupts. If a given interrupt is 
disabled (and therefore can't have caused the actual I/O interrupt),
don't try to call its handler even if its bit is set in the interrupt
register.
