-Subject: [PATCH] mm: drop page_initialized check from get_nid_for_pfn
-
-c04fc586c1a4 ("mm: show node to memory section relationship with
-symlinks in sysfs") has added means to export memblock<->node
-association into the sysfs. It has also introduced get_nid_for_pfn
-which is a rather confusing counterpart of pfn_to_nid which checks also
-whether the pfn page is already initialized (page_initialized). This
-is done by checking page::lru != NULL which doesn't make any sense at
-all. Nothing in this path really relies on the lru list being used or
-initialized. Just remove it
