I had a look at arch/powerpc/kernel/smp.c but I'm not familiar at all with 
those parts of the kernel.

See arch/powerpc/kernel/sysfs.c:topology_init.  I don't think there is
anything to do here.  You probably don't have CONFIG_HOTPLUG_CPU enabled.

I was referring to arch/ppc not arch/powerpc.

Sorry, I missed that part.

But it seems that arch/ppc doesn't support cpu hotplug anyway.

I think if there is no hotplug support then the file should not be created
in the first place.
