I just pushed two changesets to xen-ia64.bkbits.net. The first fixes a nasty mapping bug that caused strange intermittent crashes. Prior to this fix, I had not been able to compile Linux more than once without a crash. Thanks much to Matt Chapman for helping to track this one down and identify the fix.

The second enables the (global long format) VHPT for region 7. I'm not sure of the status of alternate VHPT implementations for CONFIG_VTI so this may not have an affect on VTI; however I ifdef'd some code in regionreg.c just in case. If the ifdef can go away, please let me know. If VTI is still using the non-VTI VHPT, some changes will be needed in vmx_ivt.S.
