[PATCH] add smp_setup_processor_id()
Presently, smp_processor_id() isn't necessarily set up until setup_arch(). But it's used in boot_cpu_init() and printk() and perhaps in other places, prior to setup_arch() being called. So provide a new smp_setup_processor_id() which is called before anything else, wire it up for Voyager (which boots on a CPU other than #0, and broke).
