Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma 

Pull rdma fixes from Doug Ledford:
 "Round one of 4.8 rc fixes.

  This should be the bulk of the -rc fixes for 4.8.  I only have a few
  things that are still outstanding (two ipoib bugs for which the
  solution is not yet fully known, and a few queued items that came in
  after my last push and I didn't want to delay this pull request for
  late comers again).

  Even though the patch count is kind of high, everything is minor fixes
  so the overall churn is pretty low.

  Summary:

   - minor fixes to cxgb4
   - minor fixes to mlx4
   - one minor fix each to core, rxe, isert, srpt, mlx5, ocrdma, and usnic
   - six or so fixes to i40iw fixes
   - the rest are hfi1 fixes"
