Pull infiniband reverts from Roland Dreier:
 "Last minute InfiniBand/RDMA changes for 3.19:

   - Revert IPoIB driver back to 3.18 state.  We had a number of fixes
     go into 3.19, but they introduced regressions.  We tried to get
     everything fixed up but ran out of time, so we'll try again for
     3.20.

   - Similarly, turn off the new "extended query port" verb.  Late in
     the cycle we realized the ABI is not quite right, and rather than
     freeze something in a rush and make a mistake, we'll take a bit
     more time and get it right in 3.20"
