Fix this and add some additional description.

[PATCH] s390: possible_cpus parameter 2006-02-17T21:59:27+00:00 Heiko Carstens heiko.carstens@de.ibm.com 2006-02-17T21:52:47+00:00 37a3302618a51520e2056494715ea6b4776dd8ab Introduce possible_cpus command line option. Hard sets the number of bits set in cpu_possible_map. Unlike the additional_cpus parameter this one guarantees that num_possible_cpus() will stay constant even if the system gets rebooted and a different number of cpus are present at startup.

[PATCH] s390: additional_cpus parameter 2006-02-17T21:59:26+00:00 Heiko Carstens heiko.carstens@de.ibm.com 2006-02-17T21:52:46+00:00 255acee706b333b79f593dd366f16e1f107cccc3 Introduce additional_cpus command line option. By default no additional cpu can be attached to the system anymore. Only the cpus present at IPL time can be switched on/off. If it is desired that additional cpus can be attached to the system the maximum number of additional cpus needs to be specified with this option. This change is necessary in order to limit the waste of per_cpu data structures.

[IA64] Count disabled cpus as potential hot-pluggable CPUs 2006-02-16T22:10:50+00:00 Ashok Raj ashok.raj@intel.com 2006-02-16T22:01:48+00:00 8f8b1138fc9f65e3591aac83a4ee394fef34ac1d Minor updates to earlier patch. - Added to documentation to add ia64 as well. - Minor clarification on how to use disabled cpus - used plain max instead of max_t per Andew Morton.
