Subject: alpha, exec: remove redundant set_fs(USER_DS)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6fa80900db58b547fe1cfdc77c5413091cafa7bd;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

alpha, 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.
