The last time I had a closer look at this file, defining CLOCK_TICK_RATE
was required for calculating ACT_HZ as the basis for accurate timekeeping
in the absence of a full clocksource driver. That seems to be no longer
the case, I know we talked about getting rid of this particular use
of CLOCK_TICK_RATE in the past, but I don't currently remember what
exactly happened.
