arch/alpha/kernel/smp.c calls notify_cpu_starting() from __init code.
arch/cris/arch-v32/kernel/smp.c calls notify_cpu_starting() from __init code.
arch/x86/mach-voyager/voyager_smp.c calls notify_cpu_starting() from __init code.
arch/m32r/kernel/smpboot.c calls notify_cpu_starting() from __init code.
arch/sparc/kernel/sun4d_smp.c calls notify_cpu_starting() from __init code.
arch/powerpc/kernel/smp.c calls notify_cpu_starting() from __devinit code.
arch/um/kernel/smp.c calls notify_cpu_starting() from .text code.
The other nine callers call notify_cpu_starting() from __cpuinit code.
What a mess.
