 *

 * with a constant size, but we limit that size arbitrarily to four
 * words. We call this 'large_cpumask_size'.
 *
 * Finally, some operations just want the exact limit, either because
 * they set bits or just don't have any faster fixed-sized versions. We
 * call this just 'nr_cpumask_size'.
 *
 * Note that these optional constants are always guaranteed to be at
 * least as big as 'nr_cpu_ids' itself is, and all our cpumask
 * allocations are at least that size (see cpumask_size()). The
 * optimization comes from being able to potentially use a compile-time
 * constant instead of a run-time generated exact number of CPUs.
