From 15ee2d000dd5813fcf1204b078fa276e57046b64 Mon Sep 17 00:00:00 2001 From: Mathias Krause <minipli@googlemail.com> Date: Thu, 12 Jan 2012 17:17:38 -0800 Subject: [PATCH] parisc, exec: remove redundant set_fs(USER_DS) The address limit is already set in flush_old_exec() so those calls to set_fs(USER_DS) are redundant.
