Subject[PATCH 4/5] mn10300: Get rid of set_fs(USER_DS) in sigframe setup
Date
From: Al Viro <viro@ftp.linux.org.uk>

The set_fs(USER_DS) in the signal frame setup code 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...
