Re: [PATCH] kernel: Assembly: need add prefix for h8300 architecture.

[Chen Gang]

If this implementation is correct, the implementation still can be
improved (at least, it is not quite well to hard code the architecture
related code in "kernel/" and "usr/" sub-directory).

But it seems, I have no right to add or move files, so welcome any
members help do it.

And welcome any additional suggestions or completions.

Thanks.
