Because original version return values not bigger
then initial memory allocation which does not allow
memory hotplug to function.

[PATCH 0 of 3] Miscellaneous populate-on-demand bugs
This patch series includes a series of bugs related to p2m, ept, and
PoD code which were found as part of our XenServer product testing.
Each of these fixes actual bugs, and the 3.4-based version of the patch
has been tested thoroughly. (There may be bugs in porting the patches,
but most of them are simple enough as to make it unlikely.)
Each patch is conceptually independent, so they can each

[PATCH] KVM virtio balloon driver
Hi Rusty,
It was agreed that the balloon driver should be merged through the
virtio tree, so here it goes. It depends on the config_changed patch
posted earlier.
-----
Following patch adds the KVM balloon driver.
Changes from last version:
- Get rid of global variables/structure
- Use page->lru to link ballooned pages
- Use dev_dbg/dev_printk
- Proper kthread_should_stop handling
- Move
