From: Mario Limonciello <mario.limonciello@amd.com>

This series overhauls locking and drops many unnecessarily cached
variables.

Debugging messages are also dropped in favor of more ftracing.

This series is based off superm1/linux.git bleeding-edge branch.

v3->v4:
 * Cleanups from v3 feedback
 * One new patch to drop unnecessary extra call for setting perf on cpu
   offline

Mario Limonciello (19):
  cpufreq/amd-pstate: Invalidate cppc_req_cached during suspend
  cpufreq/amd-pstate: Show a warning when a CPU fails to setup
  cpufreq/amd-pstate: Drop min and max cached frequencies
  cpufreq/amd-pstate: Move perf values into a union

  cpufreq/amd-pstate-ut: Allow lowest nonlinear and lowest to be the
    same
  cpufreq/amd-pstate-ut: Drop SUCCESS and FAIL enums
