Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/ethernet/marvell/mvneta.c The mvneta.c conflict is a case of overlapping changes, a conversion to devm_ioremap_resource() vs. a conversion to netdev_alloc_pcpu_stats. Signed-off-by: David S. Miller <davem@davemloft.net>
