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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
