 * Cpumasks provide a bitmap suitable for representing the
- * set of CPU's in a system, one bit position per CPU number.
+ * set of CPU's in a system, one bit position per CPU number.  In general,
- *
+ * only nr_cpu_ids (<= NR_CPUS) bits are valid.
- * The new cpumask_ ops take a "struct cpumask *"; the old ones
- * use cpumask_t.
- *
- * See detailed comments in the file linux/bitmap.h describing the
- * data type on which these cpumasks are based.
- *
- * For details of cpumask_scnprintf() and cpumask_parse_user(),
- * see bitmap_scnprintf() and bitmap_parse_user() in lib/bitmap.c.
- * For details of cpulist_scnprintf() and cpulist_parse(), see
- * bitmap_scnlistprintf() and bitmap_parselist(), also in bitmap.c.
- * For details of cpu_remap(), see bitmap_bitremap in lib/bitmap.c
- * For details of cpus_remap(), see bitmap_remap in lib/bitmap.c.

- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- * Note: The alternate operations with the suffix "_nr" are used
- *       to limit the range of the loop to nr_cpu_ids instead of
- *       NR_CPUS when NR_CPUS > 64 for performance reasons.
- *       If NR_CPUS is <= 64 then most assembler bitmask
- *       operators execute faster with a constant range, so
- *       the operator will continue to use NR_CPUS.
- *
- *       Another consideration is that nr_cpu_ids is initialized
- *       to NR_CPUS and isn't lowered until the possible cpus are
- *       discovered (including any disabled cpus).  So early uses
- *       will span the entire range of NR_CPUS.

- * void cpu_clear(cpu, mask)            turn off bit 'cpu' in mask
- * void cpus_setall(mask)               set all bits
- * void cpus_clear(mask)                clear all bits
- * int cpu_isset(cpu, mask)             true iff bit 'cpu' set in mask
- * int cpu_test_and_set(cpu, mask)      test and set bit 'cpu' in mask

- *
- * int cpus_equal(mask1, mask2)         Does mask1 == mask2?
- * int cpus_intersects(mask1, mask2)    Do mask1 and mask2 intersect?
- * int cpus_subset(mask1, mask2)        Is mask1 a subset of mask2?

- * int next_cpu_nr(cpu, mask)           Next cpu past 'cpu', or nr_cpu_ids

- * The structure should be defined something like this:

- *    40 lines of assembly code compiling the "for each possible cpu"
- *    loops buried in the disk_stat_read() macros calls when compiling
- *    drivers/block/genhd.c (arch i386, CONFIG_SMP=y).  So use a simple
- *    one-line #define for cpu_isset(), instead of wrapping an inline
- *    inside a macro, the way we do the other calls.
