I'm not sure where the mentioned saving of RAM is. Moving data between
sections is not supposed to make it use less memory, I believe.

Anyway, it's a good practice to mark constant data as const, to disallow
changing them at runtime by mistake, so the patch is fine. Except some
issues I commented on inline.
