Some add_memory*() users add memory in small, contiguous memory blocks. Examples include virtio-mem, hyper-v balloon, and the XEN balloon. This can quickly result in a lot of memory resources, whereby the actual resource boundaries are not of interest (e.g., it might be relevant for DIMMs, exposed via /proc/iomem to user space). We really want to merge added resources in this scenario where

From: Leon Romanovsky <leonro at nvidia.com> Changelog: v1: * Renamed _mlx5_rescan_driver to be mlx5_rescan_driver_locked like in other parts of the mlx5 driver. * Renamed MLX5_INTERFACE_PROTOCOL_VDPA to tbe MLX5_INTERFACE_PROTOCOL_VNET as a preparation to coming series from Eli C. * Some small naming renames in mlx5_vdpa. * Refactored adev index code to make Parav's SF series
