From: Ben Widawsky <benjamin.widawsky@xxxxxxxxx>
The actual correct way to think about this with the new style of page
table data structures is as the actual entry that is being indexed into
the array. "pd", and "pt" aren't representative of what the operation is
doing.
The clarity here will improve the readability of future patches.
