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

Pull rdma updates from Jason Gunthorpe:
 "A quiet cycle after the larger 5.8 effort. Substantially cleanup and
  driver work with a few smaller features this time.

   - Driver updates for hfi1, rxe, mlx5, hns, qedr, usnic, bnxt_re

   - Removal of dead or redundant code across the drivers

   - RAW resource tracker dumps to include a device specific data blob
     for device objects to aide device debugging

   - Further advance the IOCTL interface, remove the ability to turn it
     off. Add QUERY_CONTEXT, QUERY_MR, and QUERY_PD commands

   - Remove stubs related to devices with no pkey table

   - A shared CQ scheme to allow multiple ULPs to share the CQ rings of
     a device to give higher performance

   - Several more static checker, syzkaller and rare crashers fixed"
