For the obscure cases where PMD and PUD are the same size (64kB pages with 42bit VA, for example, which results in only two levels of page tables), we can't map anything as a PUD, because there is... erm... no PUD to speak of. Everything is either a PMD or a PTE. So let's only try and map a PUD when its size is different from that of a PMD.
