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

Pull rdma updates from Jason Gunthorpe:
 "Usual size of updates, a new driver, and most of the bulk focusing on
  rxe:

   - Usual typos, style, and language updates

   - Driver updates for mlx5, irdma, siw, rts, srp, hfi1, hns, erdma,
     mlx4, srp

   - Lots of RXE updates:
      * Improve reply error handling for bad MR operations
      * Code tidying
      * Debug printing uses common loggers
      * Remove half implemented RD related stuff
      * Support IBA's recently defined Atomic Write and Flush operations

   - erdma support for atomic operations

   - New driver 'mana' for Ethernet HW available in Azure VMs. This
     driver only supports DPDK"
