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

Pull rdma updates from Jason Gunthorpe:
 "A smaller set of patches, nothing stands out as being particularly
  major this cycle. The biggest item would be the new HIP09 HW support
  from HNS, otherwise it was pretty quiet for new work here:

   - Driver bug fixes and updates: bnxt_re, cxgb4, rxe, hns, i40iw,
     cxgb4, mlx4 and mlx5

   - Bug fixes and polishing for the new rts ULP

   - Cleanup of uverbs checking for allowed driver operations

   - Use sysfs_emit all over the place

   - Lots of bug fixes and clarity improvements for hns

   - hip09 support for hns

   - NDR and 50/100Gb signaling rates

   - Remove dma_virt_ops and go back to using the IB DMA wrappers

   - mlx5 optimizations for contiguous DMA regions"
