    [PATCH] Standardize pxx_page macros · 46a82b2d
    Dave McCracken authored
    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.
