Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

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.

- reg : Describes the switch address on the MII bus
- reg : Contains two fields. The first one describes the

INPUT_PROP_ACCELEROMETER

Directional axes on this device (absolute and/or relative x, y, z) represent
accelerometer data. All other axes retain their meaning. A device must not mix
regular directional axes and accelerometer axes on the same event node.
