Thanks. So may I leave all of the amd-pstate patches to you? I would gladly do that. :-)

The previous function amd_get_highest_perf() will be deprecated. It can only return 166 or 255 by cpuinfo. For platforms that support preferred core, the value of highest perf can be between 166 and 255. Therefore, it will cause amd-pstate-ut to fail when run amd_pstate_ut_check_perf().
