Subject: arm, exec: remove redundant set_fs(USER_DS)
X-Git-Tag: next-20111130~3^2~169
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e7b3824cc82ba4fd402d60ac5f7cbd0c4f83607b;p=karo-tx-linux.git

arm, exec: remove redundant set_fs(USER_DS)

The address limit is already set in flush_old_exec() so this
set_fs(USER_DS) is redundant.
