Subject: mm: vmscan: only update per-cpu thresholds for online CPU
When kswapd is awake reclaiming, the per-cpu stat thresholds are lowered
to get more accurate counts to avoid breaching watermarks. This threshold
update iterates over all possible CPUs which is unnecessary. Only online
CPUs need to be updated. If a new CPU is onlined,
refresh_zone_stat_thresholds() will set the thresholds correctly.
