For chaining, singly linked list is enough and page->index of tail page to point first object offset in the page could be replaced in run-time calculation. So, this patch change page->lru list for chaining with singly linked list via page->freelist squeeze and introduces get_first_obj_ofs to get first object offset in a page. With that, it could maintain page chaining without using page->lru.
