#     Pull rdma updates from Jason Gunthorpe:
#      "This has been a smaller cycle than normal. One new driver was
#       accepted, which is unusual, and at least one more driver remains in
#       review on the list.
#     
#       Summary:
#     
#        - Driver fixes for hns, hfi1, nes, rxe, i40iw, mlx5, cxgb4,
#          vmw_pvrdma
#     
#        - Many patches from MatthewW converting radix tree and IDR users to
#          use xarray
#     
#        - Introduction of tracepoints to the MAD layer
#     
#        - Build large SGLs at the start for DMA mapping and get the driver to
#          split them
#     
#        - Generally clean SGL handling code throughout the subsystem
#     
#        - Support for restricting RDMA devices to net namespaces for
#          containers
#     
#        - Progress to remove object allocation boilerplate code from drivers
#     
#        - Change in how the mlx5 driver shows representor ports linked to VFs
#     
#        - mlx5 uapi feature to access the on chip SW ICM memory
#     
#        - Add a new driver for 'EFA'. This is HW that supports user space
#          packet processing through QPs in Amazon's cloud"
