3.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: Borislav Petkov <b...@suse.de> commit 631e8ac18fd59722e7ceb15fceeef3f368c250f9 upstream. Andreas reports in https://bugzilla.kernel.org/show_bug.cgi?id=51741 that with his Gentoo config, acpi-cpufreq wasn't enabled and powernow-k8 couldn't handoff properly to acpi-cpufreq leading to running without P-state support (i.e., cores are constantly in P0). To alleaviate that, we need to make powernow-k8 depend on acpi-cpufreq so that acpi-cpufreq is always present.
