From f8acd944ea511af02485b1709c07ac7aac12aa48 Mon Sep 17 00:00:00 2001 From: William Lee Irwin III Date: Wed, 8 Jun 2005 15:48:52 -0700 Subject: [PATCH] [PATCH] sparc32: silence access_ok() warnings The fact that access_ok() doesn't use some of its arguments trips some unused variable warnings. This patch silences them permanently.
