Ah, my typo :-) Cool, I'll make sure to apply that before Aneesh patches.

PTRS_PER_PUD should be based on PUD_INDEX_SIZE, not PMD_INDEX_SIZE. We got away with it because PUD and PMD had the same index size, but this is no longer true with Aneesh's patchset to support a 46-bit user effective address space.
