This is the fifth revision fo the path to the VMWare balloon driver. The original
was send to linux-kernel@vger.kernel.org on 4/14/15 10.29 am PST. Please refer to
the original change for an overview.

v1:
- Initial implementation
v2
- Address suggestions by Dmitry Totoknov
- Use UINT_MAX as "infitite" rate instead of special casing -1
v3:
- Change commit comment for step 6 to better explain what impact ballooning has
on the VM performance.
v4:
- Add missing include header <linux/vmalloc.h> in step 3
v5:
- Moved to from git/torvalds/linux master to git/gregkh/char-misc char-misc-next
(4816693286d4ff9219b1cc72c2ab9c589448ebcb) and remove already applied steps
1/9 and 2/9. That changes the numbering of the patches. 3/9 is now 1/7, 4/9 is
not 2/7, etc. There were no merge issues during this transition.

Testing done: recompiled, installed, rebooted and make sure ballooning still
works

Thanks
Philip
