Subject[PATCH 3/6] cpufreq: Make acpi-cpufreq link first
Date
From: Borislav Petkov <bp@suse.de>

Now that the majority of x86 CPUs out there are supported by
acpi-cpufreq, we want it to load first and, in the AMD case, drop to
powernow-k8 only on K8s. If, however, both powernow-k8 and acpi-cpufreq
are built-in, the link order matters. Correct that.
