Pull rdma fixes from Doug Ledford:
 "This is the second pull request for the rdma subsystem.  Most of the
  patches are small and obvious.  I took two patches in that are larger
  than I wanted this late in the cycle.

  The first is the hfi1 patch that implements a work queue to test the
  QSFP read state.  I originally rejected the first patch for this
  (which would have place up to 20 seconds worth of udelays in their
  probe routine).  They then rewrote it the way I wanted (use delayed
  work tasks to wait asynchronously up to 20 seconds for the QSFP to
  come alive), so I can't really complain about the size of getting what
  I asked for :-/.

  The second is large because it switches the rcu locking in the debugfs
  code.  Since a locking change like this is done all at once, the size
  it what it is.  It resolves a litany of debug messages from the
  kernel, so I pulled it in for -rc.

  The rest are all typical -rc worthy patches I think.

  There will still be a third -rc pull request from the rdma subsystem
  this release.  I hope to have that one ready to go by the end of this
  week or early next.

  Summary:

   - a smattering of small fixes across the core, ipoib, i40iw, isert,
     cxgb4, and mlx4

   - a slightly larger group of fixes to each of mlx5 and hfi1"
