            Bug ID: 218919
           Summary: My machine enter automaticaly in ondemand but my
                    kernel config have default
                    CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE enable by
                    default
           Product: Power Management
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: cpufreq
          Assignee: linux-pm@vger.kernel.org
          Reporter: ionut_n2001@yahoo.com
        Regression: No

Hi Kernel Team,

I notice this today:

```
analyzing CPU 6:
  driver: intel_cpufreq
  CPUs which run at the same hardware frequency: 6
  CPUs which need to have their frequency coordinated by software: 6
  maximum transition latency: 20.0 us.
  hardware limits: 800 MHz - 5.00 GHz
  available cpufreq governors: conservative, ondemand, userspace, powersave,
performance, schedutil
  current policy: frequency should be within 800 MHz and 5.00 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz.

```

Ondemand is enabled on boot, but in my kernel config i have
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE at default option.

CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y

I think is not correctly this.

Reproduce:
1. intel_pstate=passive
2. intel_pstate=disable
2. intel_pstate=no_hwp
4. acpi_cpufreq

I not have installed userspace controller for scheduler.
