One of the changes necessary for shared page tables is to standardize
the pxx_page macros. pte_page and pmd_page have always returned the
struct page associated with their entry, while pte_page_kernel and
pmd_page_kernel have returned the kernel virtual address. pud_page and
pgd_page, on the other hand, return the kernel virtual address.
Shared page tables needs pud_page and pgd_page to return the actual
page structures. There are very few actual users of these functions,
so it is simple to standardize their usage.
Since this is basic cleanup, I am submitting these changes as a
standalone patch. Per Hugh Dickins' comments about it, I am
also changing the pxx_page_kernel macros to pxx_page_vaddr to clarify
their meaning.
