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

Pull rdma updates from Jason Gunthorpe:
 "Aside from the usual things this has an arch update for
  __iowrite64_copy() used by the RDMA drivers.

  This API was intended to generate large 64 byte MemWr TLPs on PCI.
  These days most processors had done this by just repeating writel() in
  a loop. S390 and some new ARM64 designs require a special helper to
  get this to generate.

   - Small improvements and fixes for erdma, efa, hfi1, bnxt_re

   - Fix a UAF crash after module unload on leaking restrack entry

   - Continue adding full RDMA support in mana with support for EQs,
     GID's and CQs

   - Improvements to the mkey cache in mlx5

   - DSCP traffic class support in hns and several bug fixes

   - Cap the maximum number of MADs in the receive queue to avoid OOM

   - Another batch of rxe bug fixes from large scale testing

   - __iowrite64_copy() optimizations for write combining MMIO memory

   - Remove NULL checks before dev_put/hold()

   - EFA support for receive with immediate

   - Fix a recent memleaking regression in a cma error path"
