Changes to v2: - drop highmem support; - fold the multicall patch into the main patch; - add another patch to extend the alloc_xenballooned_pages interface with an highmem parameter that allows the caller to explicitly request for highmem or lowmem pages; - modify gntdev to use lowmem pages only thanks to the new alloc_xenballooned_pages interface.
