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

Pull rdma updates from Doug Ledford:
 "Initial roundup of 4.6 merge window patches.

  This is the first of two pull requests.  It is the smaller request,
  but touches for more different things (this is everything but what is
  in or going into staging).  The pull request for the code in
  staging/rdma is on hold until after we decide what to do on the
  write/writev API issue and may be partially deferred until 4.7 as a
  result.

  Summary:

   - cxgb4 updates
   - nes updates
   - unification of iwarp portmapper code to core
   - add drain_cq API
   - various ib_core updates
   - minor ipoib updates
   - minor mlx4 updates
   - more significant mlx5 updates (including a minor merge conflict
     with net-next tree...merge is simple to resolve and Stephen's
     resolution was confirmed by Mellanox)
   - trivial net/9p rdma conversion
   - ocrdma RoCEv2 update
   - srpt updates"
