RE: [Xen-ia64-devel] vcpu_match_tr_entry

Hi, Tristan,

        BTW, have you tracked down the issue where you previously saw 
current stack not tracked by vTR within xenlinux? Seems following bug 
only has issue for last byte of area mapped by vTR while r13 always 
points to start of a page...

Thanks,
Kevin
