This patch series split X86_FEATURE_TSC_RELIABLE into two separate flags: X86_FEATURE_TSC_RELIABLE and X86_FEATURE_TSC_KNOWN_FREQ. This change allows us to redefine TSC features at fine granularity. This is driven by certain Intel processors/SoCs with frequency-known TSC so the whole calibration stuff should be skipped.
