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.
v2->v3:
* Drop patch 4; Intel intentionally doesn't want intel-pstate on SOHO
server
* Move symbols from patch 1 into patch 2
* Add tags
Mario Limonciello (3):
ACPI: CPPC: Add definition for undefined FADT preferred PM profile
value
cpufreq: amd-pstate: Set a fallback policy based on preferred_profile
cpufreq: amd-pstate: Add a kernel config option to set default mode
