Hi Han,
You are right again. I have not seen this cause a problem but we'll certainly fix it.

Hi, Robert,
I found out another confusing code snippet:
in void xi_invl_mfn(struct domain *d, unsigned long mfn)
if (ext && pfn < ext->large_page_aligned_size)

According to the code, it should be
if (ext && (pfn>>SPT_ENTRIES_ORDER) < ext->large_page_aligned_size)

If I made any mistake, please point it out.
