The patch titled
     Subject: init/Kconfig: enable -O3 for all arches
has been removed from the -mm tree.  Its filename was
     init-kconfig-enable-o3-for-all-arches.patch

This patch was dropped because it was nacked

------------------------------------------------------
From: Oleksandr Natalenko <oleksandr@redhat.com>
Subject: init/Kconfig: enable -O3 for all arches

Building a kernel with -O3 may help in hunting bugs like [1] and thus
using this switch should not be restricted to one specific arch only.

So let's expose it.  If for some reasone we have to hide it, lets hide it
under EXPERT.

The commit is made against next-20191210 tag.
