      Pull perf tools updates from Arnaldo Carvalho de Melo:

      Pull rdma updates from Jason Gunthorpe:
       "A usual cycle for RDMA with a typical mix of driver and core subsystem
        updates:
      
         - Driver minor changes and bug fixes for mlx5, efa, rxe, vmw_pvrdma,
           hns, usnic, qib, qedr, cxgb4, hns, bnxt_re
      
         - Various rtrs fixes and updates

         - Revert the idea that 'destroy' operations are not allowed to fail
           at the driver level. This proved unworkable from a HW perspective.
      
         - Revise how the umem API works so drivers make fewer mistakes using
           it
      
         - XRC support for qedr
