From 0b3356e19ebf9d1f340db3b4d557befea86d67f8 Mon Sep 17 00:00:00 2001
From: Warner Losh <imp@FreeBSD.org>
Date: Wed, 6 Feb 2002 16:47:06 +0000
Subject: [PATCH] Remove some unused variables, mark unused parameters as
 unused and change names of variables that shadow globally declared variables.
  This should help people doing later WARNS= fixes.
