    v850: generic timekeeping conversion
    
    Convert an arch that does not currently implement sub-jiffy timekeeping to
    use the generic timekeeping code.
    
    v850 looks like it has some intent to implement sub-jiffy timekeeping, so
    it may not yet be appropriate to try to convert, but I figured I'd get the
    maintainer's input and submit the patch for comment.
