Subject: ia64, exec: remove redundant set_fs(USER_DS)
X-Git-Tag: next-20111129~2^2~102
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e66b781d6979bdad3ab87eb8989fb65bf4bebf0;p=karo-tx-linux.git

ia64, 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.
