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

Pull rdma updates from Jason Gunthorpe:
 "Quite a small cycle this time, even with the rc8. I suppose everyone
  went to sleep over xmas.

   - Minor driver updates for hfi1, cxgb4, erdma, hns, irdma, mlx5, siw,
     mana

   - inline CQE support for hns

   - Have mlx5 display device error codes

   - Pinned DMABUF support for irdma

   - Continued rxe cleanups, particularly converting the MRs to use
     xarray

   - Improvements to what can be cached in the mlx5 mkey cache"
