Thanks. That's all I needed to hear.

I think we can forget about this patch.

Let's focus, for example, on m32r and FRAME_POINTER. The m32r entry for
that symbol reads:
bool "Compile the kernel with frame pointers"
If you say Y here [...]

0) If one is building for m32r is that all there's to it? If so, "make
menuconfig"'s search facility is serving the people building for m32r a
load of crap.

1) If it's actually more complicated than that I think that anyone
reading arch/m32r/Kconfig.debug is being duped. Things look simple but
actually they are quite complicated. I think that's just wrong.

What am I missing here?
