Sigh,
This one is under CONFIG_SMP in arch/x86/include/asm/smp.h
>>> drivers/acpi/processor_idle.c:549:4: error: implicit declaration of function 'start_cpu0' [-Werror,-Wimplicit-function-declaration]

This one is under CONFIG_HOTPLUG_CPU0 (which obviously depends on
CONFIG_SMP)
I think we can put the whole block under #ifdef CONFIG_HOTPLUG_CPU0 as
it makes zero sense otherwise. I'll send a follow-up patch.
