Conflicts:
	drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c
	net/bridge/br_multicast.c
	net/ipv6/sit.c

The conflicts were minor:

1) sit.c changes overlap with change to ip_tunnel_xmit() signature.

2) br_multicast.c had an overlap between computing max_delay using
   msecs_to_jiffies and turning MLDV2_MRC() into an inline function
   with a name using lowercase instead of uppercase letters.

3) stmmac had two overlapping changes, one which conditionally allocated
   and hooked up a dma_cfg based upon the presence of the pbl OF property,
   and another one handling store-and-forward DMA made.  The latter of
   which should not go into the new of_find_property() basic block.
