    In reality, a resurrection may not be implemented as a pure revert, but as
    the addition of a new architecture, implemented using modern features (DT,
    CCF, ...).

    Cfr. the resurrected arch/h8300, which doesn't have much in common with
    the removed one:

    $ git diff --stat v3.12..v4.2 -- arch/h8300
    [...]
    197 files changed, 3155 insertions(+), 7849 deletions(-)

    (for a total of ca. 6200 lines)

    In personal conversations with technical people, I call myself a hacker. But
    when I'm talking to journalists I just say "programmer" or something like that.
