Subject: [PATCH] arm, exec: remove redundant set_fs(USER_DS)
Date: Fri, 10 Jun 2011 15:08:57 +0200 [thread overview]
Message-ID: <1307711337-4042-1-git-send-email-minipli@googlemail.com> (raw)
In-Reply-To: <BANLkTinv1teZEHMK0qymaVdcxPOErpqSyg@mail.gmail.com>
The address limit is already set in flush_old_exec() so this
set_fs(USER_DS) is redundant.
