Some fixes for 2.6.29-rc2:

Harvey Harrison (1):
RDMA/nes: Fix for NIPQUAD removal

Randy Dunlap (1):
IB/iser: Add dependency on INFINIBAND_ADDR_TRANS

Roland Dreier (3):
mlx4_core: Fix warning from min()
IB/mlx4: Don't register IB device for adapters with no IB ports
Merge branches 'ehca', 'ipoib', 'iser', 'mlx4' and 'nes' into for-next

Stephen Rothwell (1):
IB/ehca: spin_lock_irqsave() takes an unsigned long

Yossi Etigin (2):
IPoIB: Fix loss of connectivity after bonding failover on both sides
IPoIB: Do not join broadcast group if interface is brought down
