mm: introduce putback_movable_pages()
The PATCH "mm: introduce compaction and migration for virtio ballooned pages" hacks around putback_lru_pages() in order to allow ballooned pages to be re-inserted on balloon page list as if a ballooned page was like a LRU page. As ballooned pages are not legitimate LRU pages, this patch introduces putback_movable_pages() to properly cope with cases where the isolated pageset contains ballooned pages and LRU pages, thus fixing the mentioned inelegant hack around putback_lru_pages().
