Subject: [nacked] init-kconfig-enable-o3-for-all-arches.patch removed from -mm tree
Date: Thu, 09 Jan 2020 14:02:22 -0800 [thread overview]
Message-ID: <20200109220222.hQcRs-gox%akpm@linux-foundation.org> (raw)
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.

Choosing this option will pass "-O3" to your compiler to optimize
