This will get a few post-2.6.25-rc2 fixes, mostly for the new nes driver:
Chien Tung (1):
RDMA/nes: Fix VLAN support
Glenn Streiff (1):
RDMA/nes: Fix MAC interrupt erroneously masked on ifdown
Li Zefan (1):
IB: Fix return value in ib_device_register_sysfs()
Roland Dreier (1):
RDMA/nes: Fix possible array overrun
