    Exactly, and the current Kconfig assumes that all NUMA systems are
    configured with SMP. But that does not have to be the case, especially
    with NUMA_EMU.

    Depending on SMP only is wrong IMO because CPUSETS manages both sets
    of cpus (SMP) and sets of mems (NUMA).

    So CPUSETS should either depend on SMP || NUMA or nothing.
