We can get the large mapping pte in the loop:

        if (iterator->level<  PT_PAGE_TABLE_LEVEL)
                return false;

        if (iterator->level == PT_PAGE_TABLE_LEVEL)


                if (is_large_pte(*iterator->sptep))
                        return false;

        ......
}

if level>  1 and pte.pse is set, it will return true.

And, i think this judgment is useless:
        if (iterator->level == PT_PAGE_TABLE_LEVEL)
                if (is_large_pte(*iterator->sptep))
                        return false;
since if level = 1, the pte bit7 is PAT.

Right, the logic is inverted.  I'll fix it up.
