Pull rdma updates from Jason Gunthorpe:
 "Another small cycle. Mostly cleanups and bug fixes, quite a bit
  assisted from bots. There are a few new syzkaller splats that haven't
  been solved yet but they should get into the rcs in a few weeks, I
  think.

  Summary:

   - Update drivers to use common helpers for GUIDs, pkeys, bitmaps,
     memset_startat, and others

   - General code cleanups from bots

   - Simplify some of the rxe pool code in preparation for a larger
     rework

   - Clean out old stuff from hns, including all support for hip06
     devices

   - Fix a bug where GID table entries could be missed if the table had
     holes in it

   - Rename paths and sessions in rtrs for better understandability

   - Consolidate the roce source port selection code

   - NDR speed support in mlx5"
