[PATCH] HOTPLUG_CPU: avoid hitting too many cachelines in recalc_bh_state()
Instead of using for_each_cpu(i), we can use for_each_online_cpu(i). When a CPU goes offline (ie removed from online map), it might have a non null bh_accounting.nr, so this patch adds a transfer of this counter to an online CPU counter. We already have a hotcpu_notifier, (function buffer_cpu_notify()), where we can do this bh_accounting.
