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.
