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).

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).

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.
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 :-).
