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

Pull rdma updates from Jason Gunthorpe:
 "The majority of the patches are cleanups, refactorings and clarity
  improvements.

  This cycle saw some more activity from Syzkaller, I think we are now
  clean on all but one of those bugs, including the long standing and
  obnoxious rdma_cm locking design defect. Continue to see many drivers
  getting cleanups, with a few new user visible features.

  Summary:

   - Various driver updates for siw, bnxt_re, rxe, efa, mlx5, hfi1

   - Lots of cleanup patches for hns

   - Convert more places to use refcount

   - Aggressively lock the RDMA CM code that syzkaller says isn't
     working

   - Work to clarify ib_cm

   - Use the new ib_device lifecycle model in bnxt_re

   - Fix mlx5's MR cache which seems to be failing more often with the
     new ODP code

   - mlx5 'dynamic uar' and 'tx steering' user interfaces"
