From: William Lee Irwin III Date: Wed, 8 Jun 2005 22:48:52 +0000 (-0700) Subject: [PATCH] sparc32: silence access_ok() warnings X-Git-Tag: v3.12-rc1~43115^2~98 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f8acd944ea511af02485b1709c07ac7aac12aa48;p=kernel%2Fkernel-generic.git [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.
