Jérôme Glisse a9d5adeeb4 mm/memcontrol: allow to uncharge page without using page->lru field 
HMM pages (private or public device pages) are ZONE_DEVICE page and
thus you can not use page->lru fields of those pages. This patch
re-arrange the uncharge to allow single page to be uncharge without
modifying the lru field of the struct page.

There is no change to memcontrol logic, it is the same as it was
before this patch.
