bb193d2a6b Recognize a few newer cpus (pca57, ev67 & ev68) and update systypes to
include "CUSCO" and "Eiger" while I'm at it.

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

33f86cee91 Zap some latent problems hidden by differences between KERNEL and _KERNEL.
The KAME code intruduces _KERNEL, which exposes some of them.

7ae6cdbca2 Add support for the DEC_ST6600 family of alphas. This includes the
Compaq XP1000, AlphaServer DS20, AlphaServer DS10, and DP264

This has been tested *only* on XP1000's.  I'll be interested to hear from
owners of other types of DEC_ST6600 alphas.

I'd like to thank Don Rice of Compaq for providing the documentation required
to support this platform on FreeBSD.  I'd also like to thank Doug Rabson for newbus,
and for helping me get a multiple hoses working with newbus.

897cd717a5 Add initial support for the FreeBSD/alpha kernel. This is very much a
work in progress and has never booted a real machine.  Initial
development and testing was done using SimOS (see
http://simos.stanford.edu for details).  On the SimOS simulator, this
port successfully reaches single-user mode and has been tested with
loads as high as one copy of /bin/ls :-).

Obtained from: partly from NetBSD/alpha
