------------------------------------------------------
From: Geliang Tang <geliangtang@xxxxxxx>
Subject: mm/readahead.c, mm/vmscan.c: use lru_to_page instead of list_to_page
list_to_page() in readahead.c is the same as lru_to_page() in vmscan.c.
So I move lru_to_page to internal.h and drop list_to_page().
