Since commit 4ae834f767(sched/numa: Implement NUMA home-node selection code) building a kernel with CONFIG_SMP disabled causes the following warning:
kernel/sysctl.c:259:12: warning: 'min_sched_tunable_scaling' defined but not used [-Wunused-variable] kernel/sysctl.c:260:12: warning: 'max_sched_tunable_scaling' defined but not used [-Wunused-variable] Annotate theses variables as '__maybe_unused'.
