Kernel test robot reports build breakage with commit 5f5e49e999ac ("ACPI: processor: Fix CPU0 wakeup in acpi_idle_play_dead()") when !CONFIG_HOTPLUG_CPU/!CONFIG_SMP. wakeup_cpu0() is defined under CONFIG_SMP and start_cpu0() under CONFIG_HOTPLUG_CPU which, in its turn, depend on CONFIG_SMP. Add #ifdef CONFIG_HOTPLUG_CPU to the block, this should be sufficient.
