Minchan Kim 95e3441248 mm: remain migratetype in freed page ... The page allocator caches the pageblock information in page->private while it is in the PCP freelists but this is overwritten with the order of the page when freed to the buddy allocator. This patch stores the migratetype of the page in the page->index field so that it is available at all times when the page remain in free_list. This patch adds a new call site in __free_pages_ok so it might be overhead a bit but it's for high order allocation. So I believe damage isn't hurt.
