We can now get rid of the cmm_lock and completely rely on the balloon compaction internals, which now also manage the page list and the lock. Inflated/"loaned" pages are now movable. Memory blocks that contain such pages can get offlined. Also, all such pages will be marked PageOffline() and can therefore be excluded in memory dumps using recent versions of makedumpfile. Don't switch to balloon_page_alloc() yet (due to the GFP_NOIO). Will do that separately to discuss this change in detail.
