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

Pull rdma updates from Jason Gunthorpe:
 "Usual wide collection of unrelated items in drivers:

   - Driver bug fixes and treewide cleanups in hfi1, siw, qib, mlx5,
     rxe, usnic, usnic, bnxt_re, ocrdma, iser:
       - remove unnecessary NULL checks
       - kmap obsolescence
       - pci_enable_pcie_error_reporting() obsolescence
       - unused variables and macros
       - trace event related warnings
       - casting warnings

   - Code cleanups for irdm and erdma

   - EFA reporting of 128 byte PCIe TLP support

   - mlx5 more agressively uses the out of order HW feature

   - Big rework of how state machines and tasks work in rxe

   - Fix a syzkaller found crash netdev refcount leak in siw

   - bnxt_re revises their HW description header

   - Congestion control for bnxt_re

   - Use mmu_notifiers more safely in hfi1

   - mlx5 gets better support for PCIe relaxed ordering inside VMs"
