Author: imp
Date: Wed May 1 05:46:54 2013
New Revision: 250134
URL: http://svnweb.freebsd.org/changeset/base/250134
Log:
Import virgin regdef.h from 4.4 Lite 2's sys/pmax/include/regdef.h,
expand the %sccs.include.redist.c% directive with the standard
3-clause license, and add $FreeBSD$ to keep the commit script happy.
# This may break some mips stuff, which will be fixed in the next commit.
