Move to use hmm_range_fault() instead of get_user_pags_remote() to improve performance in a few aspects: This includes: - Dropping the need to allocate and free memory to hold its output - No need any more to use put_page() to unpin the pages - The logic to detect contiguous pages is done based on the returned order, no need to run per page and evaluate. In addition, moving to use hmm_range_fault() enables to reduce page faults in the system with it's snapshot mode, this will be introduced in next patches from this series. As part of this, cleanup some flows and use the required data structures to work with hmm_range_fault().
