Subject: fs/exec.c: call arch_pick_mmap_layout() only once
X-Git-Tag: next-20140106~2^2~23
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=16d2326efdf8b6dbd839b867f76de2b21cb2d3f5;p=karo-tx-linux.git

fs/exec.c: call arch_pick_mmap_layout() only once

Currently both setup_new_exec() and flush_old_exec() issue a call to
arch_pick_mmap_layout().  As setup_new_exec() and flush_old_exec() are
always called pairwise arch_pick_mmap_layout() is called twice.

This patch removes one call from setup_new_exec() to have it only called
once.
