From fd15a1f333ff5c55be8d3d94ac4c609afe2fd79f Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 27 Mar 2017 12:28:25 +0200 Subject: s390: enable ARCH_SUPPORTS_DEFERRED_STRUCT_PAGE_INIT Deferred struct page initialization works on s390. However it makes only sense for the fake numa case, since the kthreads that initialize struct pages are started per node. Without fake numa there is just a single node and therefore no gain. However there is no reason to not enable this feature. Therefore select the config option and enable the feature in all config files.
