Hi, I am sending next version of memory hotplug support for Xen balloon driver patch. It applies to Linus' git tree, v2.6.38-rc3 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: - mm: Add add_registered_memory() to memory hotplug API, - 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, - 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 this series of patches broke machine migration under Xen. I am going to solve that problem ASAP. I do not have received any notices about other problems till now.
