With the performance governor ensuring the highest possible performance settings, userspace tools fail to make any lasting changes. In order to allow userspace tools to make modifications to the settings, the powersave governor must be in use. This makes having the powersave governor as the default convenient for systems where the intel_pstate driver is being employed. Having to enable expert mode in the kernel configuration is just a headache for such a trivial task. This patch applies to all kernel versions 2.6.38 or greater after the migration from CONFIG_EMBEDDED to CONFIG_EXPERT (6a108a14fa35). Most importantly, this applies to kernel versions 3.9 or greater when the intel_pstate driver was introduced.
