Eric Dumazet 87b08913a9 inet: move icmp_global_{credit,stamp} to a separate cache line ... icmp_global_credit was meant to be changed ~1000 times per second, but if an admin sets net.ipv4.icmp_msgs_per_sec to a very high value, icmp_global_credit changes can inflict false sharing to surrounding fields that are read mostly. Move icmp_global_credit and icmp_global_stamp to a separate cacheline aligned group.
