make balloon driver not return pages which are in [xen_start_info->nr_pages, max_pfn] on ia64. On ia64 memory might be assigned sparsely. In that case xen_start_info->nr_pages and max_pfn doesn''t match while pages which are in [xen_start_info->nr_pages, max_pfn] are used. -- yamahata _______________________________________________ Xen-devel mailing list

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
