| |
Last use of them was removed 13 years ago, when the code was converted to use CYC2NS_SCALE_FACTOR:
53d517cdbaac: ("x86: scale cyc_2_nsec according to CPU frequency")
The current TSC code uses the 'struct cyc2ns_data' scaling abstraction, the old fixed scaling approach is long gone.
This cleanup also removes the 'arbitralrily' typo from the comment, so win-win. ;-)
