freebsd-skq/sys/alpha/include/rpb.h
dfr 224577d6cf 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 :-).
