Subject: Re: [PATCH v2] rch/score/include/uapi/asm/ptrace.h: Add prefix
 'SCORE_' for related macros

These marcos are listed in advance.
Indeed, they have not been used, and the functions use them have not
be released.
I would like to keep the status even if the configure should not be used.
However, if guys think it is dirty, maybe we can remove or comment them first.

Best,
Lennox
