1e78526274 Fix problems booting large kernels on alphas. The symptom is that the kernel
loads, prints the copyright, and either hangs or locks solid.  The
PC tends to be in the data segment and the RA is in XentMM

Doug really came up with the fix, I'm just the monkey typing.  Doug says:
	The alpha can only support 64k of globals with $gp pointing at
	base+32k so that the code can use 16bit signed offsets from $gp to
	access it. ....  it is possible to have multiple .got subsections
	and the linker handles this with the relocations for 'ldgp' pseudo
	instructions.  [Without this patch] the code in exception.s has been
	linked  to use a different gp from locore.s (where pal_kgp is set).

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).

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

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

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 :-).

a3a38f0526 Header files which are linked from /usr/include to /usr/include/machine.
NetBSD's endian.h needs sys/types.h for the typedefs that are used to
get htonl() correct when a long is 64 bits.
