The following commit has been merged into the sched/core branch of tip: Commit-ID: a2cbfd46559e809c8165773b7fe8afa058b35414 Gitweb: https://git.kernel.org/tip/a2cbfd46559e809c8165773b7fe8afa058b35414 Author: Matt Fleming <matt@xxxxxxxxxxxxxxxxxxx> AuthorDate: Thu, 08 Aug 2019 20:53:00 +01:00 Committer: Ingo Molnar <mingo@xxxxxxxxxx> CommitterDate: Tue, 03 Sep 2019 09:17:36 +02:00 arch, ia64: Make NUMA select SMP While it does make sense to allow CONFIG_NUMA and !CONFIG_SMP in theory, it doesn't make much sense in practice. Follow other architectures and make CONFIG_NUMA select CONFIG_SMP. The motivation for this patch is to allow a new NUMA variable to be initialised in kernel/sched/topology.c.
