From 8e87354d01b3046aa5e1080419178191f3dce8f0 Mon Sep 17 00:00:00 2001 From: Al Viro <viro@ftp.linux.org.uk> Date: Sun, 26 Sep 2010 19:29:02 +0100 Subject: [PATCH] mn10300: get rid of set_fs(USER_DS) in sigframe setup It really has no business being there; short of a serious kernel bug we should already have USER_DS at that point. It shouldn't have been done on x86 either...
