    This attached patch might be needed too, the build breaks if
    !CONFIG_HOTPLUG_CPU and CONFIG_CPU_IDLE

    CC drivers/cpuidle/cpuidle.o
    drivers/cpuidle/cpuidle.c: In function 'cpuidle_init':
    drivers/cpuidle/cpuidle.c:272: erreur: 'cpuidle_cpu_notifier' undeclared (first use in this function)
    drivers/cpuidle/cpuidle.c:272: erreur: (Each undeclared identifier is reported only once
    drivers/cpuidle/cpuidle.c:272: erreur: for each function it appears in.)
    make[2]: *** [drivers/cpuidle/cpuidle.o] Erreur 1
    make[1]: *** [drivers/cpuidle] Erreur 2
    make: *** [drivers] Erreur 2
