Re: [PATCH 24 of 24] xen: add balloon driver

[Isaku Yamahata]

The following modification to include/xen/interface/memory.h 
removes handles related definitions.
It breaks ia64/xen compilation because ia64/xen uses memory interface
not only for balloon, but also for xen_alloc_vm_area/xen_free_vm_area().

Can it be added again?

thanks,
