Memory fragmentation introduced by ballooning might reduce significantly the number of 2MB contiguous memory blocks that can be used within a guest, thus imposing performance penalties associated with the reduced number of transparent huge pages that could be used by the guest workload. This patch-set follows the main idea discussed at 2012 LSFMMS session: "Ballooning for transparent huge

This patchset follows the main idea discussed at 2012 LSFMMS section: "Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/ to introduce the required changes to the virtio_balloon driver, as well as changes to the core compaction & migration bits, in order to allow memory balloon pages become movable within a guest. Rafael Aquini (4): mm: introduce compaction
