Subject: MIPS: Remove redundant addr_limit assignment on exec.
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=3a7136602b6fcb27073a241006cd5d029cacfafa;p=linux-edison.git

MIPS: Remove redundant addr_limit assignment on exec.

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

further explanation.]
