From: Heiko Carstens Date: Sun, 12 Feb 2006 01:56:00 +0000 (-0800) Subject: [PATCH] s390: earlier initialization of cpu_possible_map X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9733e2407ad2237867cb13c04e7d619397fa3090;p=openwrt%2Fstaging%2Fblogic.git [PATCH] s390: earlier initialization of cpu_possible_map Initiliazing of cpu_possible_map was done in smp_prepare_cpus which is way too late. Therefore assign a static value to cpu_possible_map, since we don't have access to max_cpus in setup_arch.
