native_calibrate_tsc() contains a whitelist of models that have a known TSC frequency that differs from the CPU frequency. This patchset switches the code from using magic numbers to using the defines in asm/intel-family.h and adds new processors to the whitelist.
v2: peterz, fixed typo in patch 0002. There was some question if the value was supposed to be 25000 or 24000. Experimenting on an 0x55 processor shows that 25000 is correct.
