It should do so just fine what errors are you seeing ?

CLOCK_TICK_RATE produces ACTHZ and LATCH

ACTHZ is specific to the jiffies timer (and requires CLOCK_TICK_RATE
represents the input frequency that is divided to generate the target HZ
value for the system), LATCH is used in a couple of ugly bits of x86 code
and can probably now go away.

So we now have at least two conflicting meanings for CLOCK_TICK_RATE
which again says it needs fixing not wallpapering over.
