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

Pull rdma updates from Jason Gunthorpe:
 "Lighter that normal, but the now usual collection of driver fixes and
  small improvements:

   - Small fixes and minor improvements to cxgb4, bnxt_re, rxe, srp,
     efa, cxgb4

   - Update mlx4 to use the new umem APIs, avoiding direct use of
     scatterlist

   - Support ROCEv2 in erdma

   - Remove various uncalled functions, constify bin_attribute

   - Provide core infrastructure to catch netdev events and route them
     to drivers, consolidating duplicated driver code

   - Fix rare race condition crashes in mlx5 ODP flows"
