Browse source 
A small series to clean up the mlx5 mkey code across the mlx5_core and
InfiniBand.

* branch 'mlx5_mkey':
  RDMA/mlx5: Attach ndescs to mlx5_ib_mkey
  RDMA/mlx5: Move struct mlx5_core_mkey to mlx5_ib
  RDMA/mlx5: Replace struct mlx5_core_mkey by u32 key
  RDMA/mlx5: Remove pd from struct mlx5_core_mkey
  RDMA/mlx5: Remove size from struct mlx5_core_mkey
  RDMA/mlx5: Remove iova from struct mlx5_core_mkey
