mm/swap.c: clear PageActive before adding pages onto unevictable list
As a result of commit 13f7f78981e4 ("mm: pagevec: defer deciding which LRU to add a page to until pagevec drain time"), pages on unevictable lists can have both of PageActive and PageUnevictable set. This is not only confusing, but also corrupts page migration and shrink_[in]active_list. This patch fixes the problem by adding ClearPageActive before adding pages into unevictable list. It also cleans up VM_BUG_ONs. Signed-off-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Cc: Mel Gorman <mgorman@suse.de> Cc: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: "Kirill A.
