Could you explain further?

when xen/ia64 fails to read a bundle.
Xen/ia64 reflected dtlb miss before my change.
Is it correct to reflect dtlb miss?
No this was just a hack that worked. It does need

There are the following choices for right fix, I think.
A. use hypercall instead of hyperprivop.
B. introduce new flag for hyperprivop instread VPSR.ic as Tristan
proposed.
C. use one of itr to map vDSO.
D. abondan vDSO
