We can get the large mapping pte in the loop:

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.
