So something's seriously confusing or missing here because if you fault on a 2M host page and the underlying RMP entries are 4K then you can use pte_index(). If the host page is 1G and the underlying RMP entries are 2M, pmd_index() should work here too. But this piecemeal back'n'forth doesn't seem to resolve this so I'd like to ask you pls to sit down, take your time and give a detailed example of the two possible cases and what the difference is between pte_/pmd_index and your way. Feel free to add actual debug output and paste it here. Thanks. -- Sent from a small device: formatting sux and brevity is inevitable.
