3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joonsoo Kim <js1304@gmail.com>
commit dc32f63453f56d07a1073a697dcd843dd3098c09 upstream.
Commit a6bc32b89922 ("mm: compaction: introduce sync-light migration for use by compaction") changed the declaration of migrate_pages() and migrate_huge_pages().
But it missed changing the argument of migrate_huge_pages() in soft_offline_huge_page(). In this case, we should call migrate_huge_pages() with MIGRATE_SYNC.
Additionally, there is a mismatch between type the of argument and the function declaration for migrate_pages().
