Subject: [PATCH R4 0/7] xen/balloon: Memory hotplug support for Xen balloon driver

Hi,

I am sending next version of memory hotplug
support for Xen balloon driver patch. It applies
to Linus' git tree, v2.6.38-rc8 tag. Most of
suggestions were taken into account. Thanks for
everybody who tested and/or sent suggestions
to my work.

There are a few prerequisite patches which fixes
some problems found during work on memory hotplug
patch or add some futures which are needed by
memory hotplug patch.

Full list of fixes/futures:
  - xen/balloon: Removal of driver_pages,
  - xen/balloon: HVM mode support,
  - xen/balloon: Migration from mod_timer() to schedule_delayed_work(),
  - xen/balloon: Protect against CPU exhaust by event/x process,
  - xen/balloon: Minor notation fixes,
  - mm: Extend memory hotplug API to allow memory hotplug in virtual guests,
  - xen/balloon: Memory hotplug support for Xen balloon driver.

Additionally, I suggest to apply patch prepared by Steffano Stabellini
(https://lkml.org/lkml/2011/1/31/232) which fixes memory management
issue in Xen guest. I was not able boot guest machine without
above mentioned patch.

I have received notice that previous series of patches broke
machine migration under Xen. I am going to confirm that and
solve that problem ASAP. I do not have received any notices
about other problems till now.

Daniel
