[Xen-ia64-devel] RE: PATCH: allow domain to set shared_info address

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

Can shared_info be changed randomly at any time by
a domain?  Will this cause any problems?  If this
hypercall can/should be called only very early during
boot, it would be good to add some checks to disallow
it from being called at a later time.
