Eric Dumazet 8a14342683 [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.
