Subject: ARM: exec: remove redundant set_fs(USER_DS)
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e88443cdfc61af5cd22d6aeb245ee94833c473bc;p=openwrt%2Fstaging%2Fblogic.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.
