Subject: [PATCH v5 0/7]  Fifth revision of the performance improvement patch to the VMware balloon driver

This is the fifth revision fo the path to the VMWare balloon driver. The original
was send to linux-kernel@...r.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
