Again, there's no reason to have both of these. Pick one and stick with
it.

The debugging here looks broken, just use pr_debug() and DEBUG as normal,
then you can kill off this DEBUG_BFIN_RELOC thing.

You may want to change this to CONFIG_ACCESS_CHECK instead, it's a bit
more intuitive than checking ! CONFIG_NO_ACCESS_CHECK.

The RCS tags should be killed off as well, it's clear that they don't
really mean anthing, even in this case.

Here you have low level.

This is generated by Kbuild, there's no point in including it in the

Should these be in asm-offsets?
The rest of the patch looks good, this is certainly an improvement!
