Subject: [PATCH] powerpc: Define NR_CPUS all the time
Date: Fri, 7 May 2021 09:24:43 +0000 (UTC) [thread overview]
Message-ID: <afef0ec65a8ba8651bf4f6e4f4f08a8b6991dbfb.1620379469.git.christophe.leroy@csgroup.eu> (raw)
include/linux/threads.h defines a default value for CONFIG_NR_CPUS
but suggests the architectures should always define it.
So do it, when CONFIG_SMP is not selected set CONFIG_NR_CPUS to 1.
