(*) 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.

If the cpuset flag file 'memory_migrate' is set true, then when
tasks are attached to that cpuset, any pages that task had
allocated to it on nodes in its previous cpuset are migrated
to the tasks new cpuset.  Depending on the implementation,
this migration may either be done by swapping the page out,
so that the next time the page is referenced, it will be paged
into the tasks new cpuset, usually on the node where it was
referenced, or this migration may be done by directly copying
the pages from the tasks previous cpuset to the new cpuset,

the cpuset is preserved during these migration operations if possible.
For example if the page was on the second valid node of the prior cpuset
then the page will be placed on the second valid node of the new cpuset.

Also if 'memory_migrate' is set true, then if that cpusets
'mems' file is modified, pages allocated to tasks in that
cpuset, that were on nodes in the previous setting of 'mems',
will be moved to nodes in the new setting of 'mems.'  Again,
depending on the implementation, this might be done by swapping,
