Active mode for amd-pstate has shown enough success now that it makes sense
to enable it by default on client systems.

This series introduces a new kernel configuration option to set the default
policy for amd-pstate modes for a kernel.

Server systems will by identified by the PM preferred profile and still be
set as disabled by default for now.

Mario Limonciello (4):
  ACPI: CPPC: Add a symbol to check if the preferred profile is a server
  cpufreq: amd-pstate: Set a fallback policy based on preferred_profile
  cpufreq: amd-pstate: Add a kernel config option to set default mode
  cpufreq: intel_pstate: Use the acpi_pm_profile_server() symbol
