However, PUD_PAGE_SIZE and PUD_PAGE_MASK, which are set from PUD_SHIFT, are defined in page_64_types.h, which can be used by 64-bit kernel only. Move PUD_PAGE_SIZE and PUD_PAGE_MASK to page_types.h so that they can be used by any x86 kernels as well. Signed-off-by: Toshi Kani Cc: Juergen Gross Cc: Thomas Gleixner Cc: H.
