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

Conflicts: Documentation/devicetree/bindings/net/micrel-ks8851.txt net/core/netpoll.c The net/core/netpoll.c conflict is a bug fix in 'net' happening to code which is completely removed in 'net-next'. In micrel-ks8851.txt we simply have overlapping changes. Signed-off-by: David S. Miller <davem@davemloft.net>
