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

Pull rdma updates from Jason Gunthorpe:
 "Usual collection of small improvements and fixes, nothing especially
  stands out to me here.

  The new multipath PCI feature is a sign of things to come, I think we
  will see more of this in the next 10 years. Broadcom and HNS continue
  to update their drivers for their new HW generations.

  Summary:

   - Bug fixes and minor improvments in cxgb4, siw, mlx5, rxe, efa, rts,
     hfi, erdma, hns, irdma

   - Code cleanups/typos/etc. Tidy alloc_ordered_workqueue() calls

   - Multipath PCI for mlx5

   - Variable size work queue, SRQ changes, and relaxed ordering for new
     bnxt HW

   - New ODP fault resolution FW protocol in mlx5

   - New 'rdma monitor' netlink mechanism"
