- * cpu_possible_map - all NR_CPUS bits set
- * cpu_present_map - has bit 'cpu' set iff cpu is populated
- * cpu_online_map - has bit 'cpu' set iff cpu available to scheduler
- * #else
- * cpu_possible_map - has bit 'cpu' set iff cpu is populated
- * cpu_present_map - copy of cpu_possible_map
- * cpu_online_map - has bit 'cpu' set iff cpu available to scheduler
- * #endif
- *
- * In either case, NR_CPUS is fixed at compile time, as the static
- * size of these bitmaps. The cpu_possible_map is fixed at boot
- * time, as the set of CPU id's that it is possible might ever
- * be plugged in at anytime during the life of that system boot.
- * The cpu_present_map is dynamic(*), representing which CPUs
- * are currently plugged in. And cpu_online_map is the dynamic
- * subset of cpu_present_map, indicating those CPUs available
- * for scheduling.
- *
- * If HOTPLUG is enabled, then cpu_possible_map is forced to have
- * all NR_CPUS bits set, otherwise it is just the set of CPUs that
- * ACPI reports present at boot.
- *
- * If HOTPLUG is enabled, then cpu_present_map varies dynamically,
- * depending on what ACPI reports as currently plugged in, otherwise
- * cpu_present_map is just a copy of cpu_possible_map.
- *
- * (*) Well, cpu_present_map is dynamic in the hotplug case. If not
- * hotplug, it's a copy of cpu_possible_map, hence fixed at boot.
- *
- * Subtleties:
- * 1) UP arch's (NR_CPUS == 1, CONFIG_SMP not defined) hardcode
- * assumption that their single CPU is online. The UP
- * cpu_{online,possible,present}_maps are placebos. Changing them
- * will have no useful affect on the following num_*_cpus()
- * and cpu_*() macros in the UP case. This ugliness is a UP
- * optimization - don't waste any instructions or memory references
- * asking if you're online or how many CPUs there are if there is
- * only one CPU.
- * 2) Most SMP arch's #define some of these maps to be some
- * other map specific to that arch. Therefore, the following
- * must be #define macros, not inlines. To see why, examine
- * the assembly code produced by the following. Note that
- * set1() writes phys_x_map, but set2() writes x_map:
- * int x_map, phys_x_map;
- * #define set1(a) x_map = a
- * inline void set2(int a) { x_map = a; }
- * #define x_map phys_x_map
- * main(){ set1(3); set2(5); }
