[SRU][N][PATCH 0/2] power: intel_pstate: HWP interrupt support for maximum ratio changed

[Thibault Ferrante]

[ Impact ]

 * Performance improvement for intel hardware with dynamic HWP (Hardware P-States)

[ Fix ]

Upstream commits support dynamic HWP:
  7ea81936b853 x86/cpufeatures: Add HWP highest perf change feature flag
  d845cd901b28 cpufreq: intel_pstate: Support highest performance change interrupt

[ Test Plan ]

 * check on supported hardware that the correct max cpu freq is detected

[ Where problems could occur ]

 * Regression on intel CPU frequency
