It's not a pfn index though - pfns are physical, this is virtual still.
It's the index into the pte page ... vaddr_to_pte_page_index I guess,
but pte_index seems easier ;-)

Right, yes ... but that's still really just a physical address (>> PAGE_SHIFT).
I was trying to emphasize phys vs virt. But I was being needlessly obtuse ;-)
