[PATCH 0/4] x86/tsc: add X86_FEATURE_TSC_KNOWN_FREQ flag and hardware related changes

[Bin Gao]

This patch series adds X86_FEATURE_TSC_KNOWN_FREQ flag and modifies
Intel Atom SoC related TSC codes to use the new TSC_KNOWN_FREQ flag
and the existed TSC_RELIABLE flag.

Bin Gao (4):
  x86/tsc: add X86_FEATURE_TSC_KNOWN_FREQ flag
  x86/tsc: mark TSC frequency determined by CPUID as known
  x86/tsc: mark Intel ATOM_GOLDMONT TSC reliable
  x86/tsc: set TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Atom SoCs
