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@xxxxxxxxxx> 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.
