The patch is against HEAD, but it can be applied to 3.0 branch too.
I don't think it's in 3.0.2, as it is no time to be included.  It will
be 3.0.3, though.

Stock GCC does not compile the kernel.  Currently arch/sh/Makefile
uses -m4-nofpu, and we need some change to define __SH4___ and
undefine __sh3__ for that flag, and it's not binary compatible to -m4,
as Masahiro Abe pointed out.

It takes long time to solve this problem, but I have done the work.
I don't know why you object the change.

I agree that migrating GNU toolchain is hard thing.  But eventually we
have to migrate (or proceed) in some time.

If you have your specific need (or customer) to stick old GNU
Toolchain and old kernel, that's no problem, you yourself could have
your own sets of toolchain and some small patch to the kernel.  Less
is the better, you know, but it's not _zero_ in this real world.
Everyone has that, and cooperate to minimize the diffusion.
