After the cleanup in r8a7779_smp_prepare_cpus(), the only remaining caller of r8a7779_platform_cpu_kill() is in an ifdef, which leads to a build warning without CONFIG_HOTPLUG_CPU: arch/arm/mach-shmobile/smp-r8a7779.c:26:12: error: 'r8a7779_platform_cpu_kill' defined but not used [-Werror=unused-function] This moves the function inside of that #ifdef to avoid the warning.
