From f5461d41b129fefc48ff4c9ded82554394de9bf0 Mon Sep 17 00:00:00 2001
From: Kenneth R Westerback <krw@cvs.openbsd.org>
Date: Sat, 6 Oct 2007 23:50:56 +0000
Subject: Simpliest memset(,0,) -> M_ZERO changes. One (caddr *) cast removal,
 otherwise just adding M_ZERO to malloc() and removing the immediately
 adjacent memset(,0,).
