Subject[PATCH v2 2/4] x86, asm: Move PUD_PAGE macros to page_types.h
Date
PUD_SHIFT is defined according to a kernel configuration, which
allows it be commonly used by any kernels. However, PUD_PAGE_SIZE
and PUD_PAGE_MASK, which are calculated from PUD_SHIFT, are defined
in page_64_types.h, which allows them be used by a 64-bit kernel
only.

Move PUD_PAGE_SIZE and PUD_PAGE_MASK to page_types.h so that they
can be used by any kernels as well.
