Yep, this stops the warning and everything looks fine.  I'd say you
put it there because it gets lumped with

        .section __special_page_section,"ax"

from head.S, so in the end the whole thing ends up with AWX.

  [21] .data.page_aligne PROGBITS         a000000100610000  00620000
       0000000000008d50  0000000000000000 WAX       0     0     1

You're of course right about wasting memory with a separate section, I
didn't think of that. 

Maybe just change it and add something like 

Even though this is put with __special_page_section which is given
attributes "ax" (head.S), gas will match anything with a prefix
'.data.' as a data special section.  Thus to stop unnecessary warning
about changing attributes, we use the .data section standard
attributes "aw" when creating gate-data.o
