Subject: [patch 45/59] bonding: ARP monitoring broken on x86_64

-stable review patch. If anyone has any objections, please let us know.
------------------

From: Andy Gospodarek <[email protected]>

While working with the latest bonding code I noticed a nasty problem that
will prevent arp monitoring from always functioning correctly on x86_64
systems. Comparing ints to longs and expecting reliable results on x86_64
is a bad idea. With this patch, arp monitoring works correctly again.
