I don't like the names. The accounting is also wrong for non-order-0
allocations. It should be

mod_lruvec_page_state(page, NR_PAGETABLE, compound_nr(page))

but it's probably better to change the API to pass in the number of
pages instead of recalculating it.

I can't think of a good name. What's wrong with just adding

static inline bool pgtable_pud_page_ctor(struct page *page)

to go along with the pte and pmd variants?
