Hi Alex,
	With this fix and previous patches, we can boot VTi successfully with new Qemu on xen-ia64-unstable.hg 's tip(10784). Should we make xen-unstable.hg sync with xen-ia64-unstable.hg happen next step?  
Thanks & Best Regards

Hi, Christian
	Thank you for your comments. But I check the patch on tip. Seems the following line not in upstream. I don't know why this part was lost when check-in.
