53ia64 and x86_64 use the number of disabled local apics in ACPI tables MADT
54to determine the number of potentially hot-pluggable cpus. The implementation
55should only rely on this to count the #of cpus, but *MUST* not rely on the
56apicid values in those tables for disabled apics. In the event BIOS doesnt
57mark such hot-pluggable cpus as disabled entries, one could use this
58parameter "additional_cpus=x" to represent those cpus in the cpu_possible_map.
