This just restricts the cpu_possible_map to a more reasonable number. We now count the number of disabled cpus in MADT as potentially hotpluggable cpus. In case thats not true, parameter additional_cpus=x can be used at startup to add extra bits to cpu_possible_map. Will be good to fix it before 2.6.16 gets released. Other arch code is mostly checked in already I think. Cheers, ashok
