    SubjectRe: [PATCH 2/3 RESEND] ptrace: cleanup address space conversion on ptrace_request()

    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.
