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

Pull rdma updates from Jason Gunthorpe:
 "This is quite a small cycle, no major series stands out. The HNS and
  rxe drivers saw the most activity this cycle, with rxe being broken
  for a good chunk of time. The significant deleted line count is due to
  a SPDX cleanup series.

  Summary:

   - Various cleanup and small features for rtrs

   - kmap_local_page() conversions

   - Driver updates and fixes for: efa, rxe, mlx5, hfi1, qed, hns

   - Cache the IB subnet prefix

   - Rework how CRC is calcuated in rxe

   - Clean reference counting in iwpm's netlink

   - Pull object allocation and lifecycle for user QPs to the uverbs
     core code

   - Several small hns features and continued general code cleanups

   - Fix the scatterlist confusion of orig_nents/nents introduced in an
     earlier patch creating the append operation"
