From: Alexey Brodkin Date: Wed, 29 Nov 2017 08:21:45 +0000 (+0300) Subject: ARC: Enable machine_desc->init_per_cpu for !CONFIG_SMP X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2f24ef7413a4d91657ef04e77c27ce0b313e6c95;p=openwrt%2Fstaging%2Fblogic.git ARC: Enable machine_desc->init_per_cpu for !CONFIG_SMP machine_desc->init_per_cpu() hook is supposed to be per cpu initialization and would seem to apply equally to UP and/or SMP. Infact the comment in header file seems to suggest it works for UP too, which was not the case and this patch. This enables !CONFIG_SMP build for platforms such as hsdk.
