    I think most important part is update_times() cleanup (to avoid
    jiffies/wall_jiffies mismatch) and it (and x86_64 part) seems not
    conflict with john's work for now.

    I and Ralf talked a bit about the jiffies issue. Making an union
    containing jiffies and jiffies_64 looks good to avoid such an
    optimization problem, but it would affect so many existing codes.
