    For dependencies, branch based on 'mellanox/mlx5-next' of
    git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux.git
    
    Pull Dump and fill MKEY from Leon Romanovsky:
    
    ====================
    MLX5 IB HCA offers the memory key, dump_fill_mkey to increase performance,
    when used in a send or receive operations.
    
    It is used to force local HCA operations to skip the PCI bus access, while
    keeping track of the processed length in the ibv_sge handling.
    
    In this three patch series, we expose various bits in our HW spec
    file (mlx5_ifc.h), move unneeded for mlx5_core FW command and export such
    memory key to user space thought our mlx5-abi header file.
    ====================
    
    Botched auto-merge in mlx5_ib_alloc_ucontext() resolved by hand.
    
    * branch 'mlx5-dump-fill-mkey':
      IB/mlx5: Expose dump and fill memory key
      net/mlx5: Add hardware definitions for dump_fill_mkey
      net/mlx5: Limit scope of dump_fill_mkey function
