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

Pull rdma updates from Jason Gunthorpe:
 "This cycle saw a focus on rxe and bnxt_re drivers:

   - Code cleanups for irdma, rxe, rtrs, hns, vmw_pvrdma

   - rxe uses workqueues instead of tasklets

   - rxe has better compliance around access checks for MRs and rereg_mr

   - mana supportst he 'v2' FW interface for RX coalescing

   - hfi1 bug fix for stale cache entries in its MR cache

   - mlx5 buf fix to handle FW failures when destroying QPs

   - erdma HW has a new doorbell allocation mechanism for uverbs that is
     secure

   - Lots of small cleanups and rework in bnxt_re:
       - Use the common mmap functions
       - Support disassociation
       - Improve FW command flow
       - support for 'low latency push'"
