But sounds like your fix to mark anything going to init.rodata as const
is correct since it is rodata. I was originally thinking this is somehow
related to __init vs __initconst, but it's for __initconst only, and
we should use const there as it's read only.

Let me take another look at your patches and make sure everything
compiles OK, I don't think we're using __initconst in that many places.
