Subject: [PATCH 0/2] amd-pstate: amd_pstate related fixes

This 2 patch series has the following 2 fixes for amd_pstate:
- Currently, amd_pstate sets CPPC enable MSR for a single CPU. But ACPI
  specification recommends driver to set CPPC enable register per-core.
  Align amd_pstate driver with the spec.

- Remove some extra checks for active mode which are not required.

Wyes Karny (2):
  cpufreq/amd-pstate: Write CPPC enable bit for each core
  cpufreq/amd-pstate: Remove unnecessary active state checks
