This patch represents TSC freqeuency in KHz using a 32-bit unsigned integer.
The conversion macros between ticks and us/ms are changed to inline functions to
enforce the types of the input parameters. Note that us_to_ticks accepts only
uint32_t (~4K us at most) and never overflows.
Results of some unit tests on the conversion functions:
calibrate_tsc, tsc_khz=1881600
64us -> ticks: 120422
64us -> ticks -> us: 63
511us -> ticks: 961497
511us -> ticks -> us: 510
1280000 ticks -> us: 680
1280000 ticks -> us -> ticks: 1279488
