The Patch 3~6 convert several more migration functions to use folio. The patch 7 remove PageHead() check to make hugetlb to migrate the entire hugetlb page instead of -EACCES errno return when passed the address of a tail page. The patch 8 cleanup to unify and simplify code a bit in add_page_for_migration() v2: Thanks for all comments and advise from Matthew, Hugh, Zi, Mike, Huang. - keep page_mapcount() check and remove specific assert for PageTransHuge page. - separate patch7 to migrate the entire hugetlb page if a tail page passed, which unified the behavior between HUGETLB and THP when move_page().
