How about these patches instead of this one?

1. add folio_split() backend code, including __folio_split_without_mapping() and __split_folio_to_order();
2. change split_huge_page_to_list_to_order() to use the backend code in 1;
3. add folio_split();
4. remove __split_huge_page() and __split_huge_page_tail().
