vmw_balloon: Compaction support
Add support for compaction for VMware balloon. Since unlike the virtio balloon, we also support huge-pages, which are not going through compaction, we keep these pages in vmballoon and handle this list separately. We use the same lock to protect both lists, as this lock is not supposed to be contended. Doing so also eliminates the need for the page_size lists. We update the accounting as needed to reflect inflation, deflation and migration to be reflected in vmstat. Since VMware balloon now provides statistics for inflation, deflation and migration in vmstat, select MEMORY_BALLOON in Kconfig.

This is VMware physical memory management driver which acts
like a "balloon" that can be inflated to reclaim physical pages
