  Log:
  Notify the OS that we're taking over Px states in acpi_perf(4) instead of
  doing it in the cpu driver.  The previous code was incorrect anyway since
  this value controls Px states, not throttling as the comment said.  Since
  we didn't support Px states before, there was no impact.  Also, note that
  we delay the write to SMI_CMD until after booting is complete since it
  sometimes triggers a change in the frequency and we want to have all
  drivers ready to detect/handle this.
