* See detailed comments in the file linux/bitmap.h describing the

* 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.
