Message-ID <[email protected]>
We want to rework how pgd_page_vaddr() behaves for generic compile-time
folded page tables by disallowing its use and triggering a compile-time
error when it is used improperly, ensuring that the actual first-level
pXd_pgtable() function is used instead.

For this, change usage of pgd_page_vaddr() to pud_pgtable() for
the functions used when PGTABLE_LEVELS=3.

There should be no functional change.
