I cannot see any requirement for that. I will say it is tested and
inter-operates happily with CONFIG_THUMB_KERNEL, but because it's constrained to
am335x and am437x I don't think there are unknown situations where every single
instruction must be THUMB.

It should be static.

No, I just was following the ifdef example set by others in the file, a stub
would be cleaner I agree.
