-/* cycles to nsec conversions taken from arch/i386/kernel/timers/timer_tsc.c,
- * converted to use kHz by Kevin Hilman */
-/* convert from cycles(64bits) => nanoseconds (64bits)
- *  basic equation:
- *              ns = cycles / (freq / ns_per_sec)
- *              ns = cycles * (ns_per_sec / freq)
- *              ns = cycles * (10^9 / (cpu_khz * 10^3))
- *              ns = cycles * (10^6 / cpu_khz)
- *
- *      Then we use scaling math (suggested by george at mvista.com) to get:
- *              ns = cycles * (10^6 * SC / cpu_khz / SC
- *              ns = cycles * cyc2ns_scale / SC
- *
- *      And since SC is a constant power of two, we can convert the div
- *  into a shift.
