Hi,

According to talk with Zi Yan [1], this patch set changes the return
value of migrate_pages() to avoid returning a number which is larger
than the number of pages the users tried to migrate by move_pages() syscall.
Also fix the hugetlb migration stats and migration stats in
trace_mm_compaction_migratepages(). Please help to review. Thanks.
