Yes, same page now. On this point, we have to trust. Hey, para-domain 
is para-virtualized so it should be cooperative. Cooperative here means 
para-domain needs to conform with para-interfaces defined by Xen. One 
of Xen's responsibility is to service domain's request (good or bad) and 
ensure bad request from one crazy domain not interfering with others. 
You know there're infinite approaches to destroy domain itself easier than 
passing a bogus va at grant unmap. :-)

Thanks,
Kevin
