McKenney" A number of mainstream CPU families are no longer capable of building kernels having CONFIG_SMP=y and CONFIG_HOTPLUG_CPU=n, so this commit removes this combination from the rcutorture scenarios having it. People wishing to try out this combination may still do so using the "--kconfig CONFIG_HOTPLUG_CPU=n CONFIG_SUSPEND=n CONFIG_HIBERNATION=n" argument to the tools/testing/selftests/rcutorture/bin/kvm.sh script that is used to run rcutorture.
