Where the fault address may be not aligned with the huge\npage size.  Then, folio_zero_user() may call clear_gigantic_page() with\nthe address, while clear_gigantic_page() requires the address to be huge\npage size aligned.  So, this may cause memory corruption or information\nleak, addtional, use more obvious naming 'addr_hint' instead of 'addr' for\nclear_gigantic_page()."
