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
