After I've checked all arch_ptrace() code, I can think there is no specific
reason @addr and @data to be signed long types. Most of archs use them
as if they were unsigned. So I'll prepare a patch series to change this
and some cleanups of ptrace_request() and all of arch_ptrace() if no
objection exists.

Thanks.
