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

Pull rdma updates from Jason Gunthorpe:
 "This is significantly bug fixes and general cleanups. The noteworthy
  new features are fairly small:

   - XRC support for HNS and improves RQ operations

   - Bug fixes and updates for hns, mlx5, bnxt_re, hfi1, i40iw, rxe, siw
     and qib

   - Quite a few general cleanups on spelling, error handling, static
     checker detections, etc

   - Increase the number of device ports supported beyond 255. High port
     count software switches now exist

   - Several bug fixes for rtrs

   - mlx5 Device Memory support for host controlled atomics

   - Report SRQ tables through to rdma-tool"
