Message-Id: <E1OzvyA-0002pg-84@ZenIV.linux.org.uk> Date: Sun, 26 Sep 2010 19:29:02 +0100 From: Al Viro <viro@....linux.org.uk> To: linux-kernel@...r.kernel.org Cc: dhowells@...hat.com, torvalds@...ux-foundation.org Subject: [PATCH 4/5] 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...
