+(*) Option valid only for following architectures
+- x86_64, ia64, s390

 ia64 and x86_64 use the number of disabled local apics in ACPI tables MADT
 to determine the number of potentially hot-pluggable cpus. The implementation
 should only rely on this to count the #of cpus, but *MUST* not rely on the
 apicid values in those tables for disabled apics. In the event BIOS doesnt
 mark such hot-pluggable cpus as disabled entries, one could use this
 parameter "additional_cpus=x" to represent those cpus in the cpu_possible_map.
 
+s390 uses the number of cpus it detects at IPL time to also the number of bits
+in cpu_possible_map. If it is desired to add additional cpus at a later time
+the number should be specified using this option or the possible_cpus option.
