True, but this also save some amount of ram for some distro kernels.
If we keep this static NR_CPUS thing, we might be able to free
the end of table, for other per_cpu users ?
if (nr_cpus_ids < NR_CPUS) {
per_cpu_free_static_zone(&update_shares_data[nr_cpus_ids],
sizeof(long)*(NR_CPUS - nr_cpus_ids));
