That fixes mmzone.h but it still doesn't produce kernel that
will build without error:

arch/i386/mm/discontig.c: In function ‘zone_sizes_init’:
arch/i386/mm/discontig.c:388: warning: implicit declaration of function ‘get_zholes_size’
arch/i386/mm/discontig.c:388: warning: assignment makes pointer from integer without a cast

and:
  LD      .tmp_vmlinux1
arch/i386/mm/built-in.o: In function `zone_sizes_init':
(.init.text+0xd05): undefined reference to `get_zholes_size'
make: *** [.tmp_vmlinux1] Error 1

Same .config as in previous email.
