Subject: cris, exec: remove redundant set_fs(USER_DS)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5ec80e50e11bcc3f39e47b9dc73110dbc58e4780;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

cris, exec: remove redundant set_fs(USER_DS)

The address limit is already set in flush_old_exec() so those calls to
set_fs(USER_DS) are redundant.
