Subject: [PATCH] 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.
