Pull rdma updates from Doug Ledford:
 "This is my initial round of 4.4 merge window patches.  There are a few
  other things I wish to get in for 4.4 that aren't in this pull, as
  this represents what has gone through merge/build/run testing and not
  what is the last few items for which testing is not yet complete.

   - "Checksum offload support in user space" enablement
   - Misc cxgb4 fixes, add T6 support
   - Misc usnic fixes
   - 32 bit build warning fixes
   - Misc ocrdma fixes
   - Multicast loopback prevention extension
   - Extend the GID cache to store and return attributes of GIDs
   - Misc iSER updates
   - iSER clustering update
   - Network NameSpace support for rdma CM
   - Work Request cleanup series
   - New Memory Registration API"
