I have the same problem. Looking through the code, it looks like the
throttling code from acpi_cpu.c basically got moved into acpi_perf.c.
No. acpi throttling code moved to acpi_throttle.c. acpi_perf.c is a
new driver. In any case, a powernow.c driver will eventually be
committed to provide this functionality. You can keep using acpi_ppc
