Why cannot we simply provide a constructor for each page by the caller
if there are special requirements? we currently have alt_map to do
struct page allocation but nothing really prevents to make it more
generic and control both allocation and initialization whatever suits a
specific usecase. I really do not want make special cases here and
there.
