Conflicts: drivers/net/ethernet/mellanox/mlx4/cmd.c net/core/fib_rules.c net/ipv4/fib_frontend.c The fib_rules.c and fib_frontend.c conflicts were locking adjustments in 'net' overlapping addition and removal of code in 'net-next'. The mlx4 conflict was a bug fix in 'net' happening in the same place a constant was being replaced with a more suitable macro. Signed-off-by: David S. Miller <davem@davemloft.net>
