* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband:
  IB/iser: Add dependency on INFINIBAND_ADDR_TRANS
  IPoIB: Do not join broadcast group if interface is brought down
  RDMA/nes: Fix for NIPQUAD removal
  IPoIB: Fix loss of connectivity after bonding failover on both sides
  IB/mlx4: Don't register IB device for adapters with no IB ports
  mlx4_core: Fix warning from min()
  IB/ehca: spin_lock_irqsave() takes an unsigned long
