[ Upstream commit 975776841e689dd8ba36df9fa72ac3eca3c2957a ]
kernel/sched/isolation.c obviously makes no sense without CONFIG_SMP, but the Kconfig entry we have right now:
config CPU_ISOLATION bool "CPU isolation" depends on SMP || COMPILE_TEST
allows the creation of pointless .config's which cause build failures.
