- * 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

- *
- * Another consideration is that nr_cpu_ids is initialized

- * discovered (including any disabled cpus). So early uses
- * will span the entire range of NR_CPUS.
