ACPI: Load acpi-cpufreq from processor driver automatically
The only left over hole in automatic cpufreq driver loading was the loading of ACPI cpufreq. This driver should be loaded when ACPI supports a _PDC method and the CPU vendor wants to use acpi cpufreq. Simply add a request module call to the acpi processor core driver when this is true. This seems like the simplest solution for this. Cc: Len Brown <lenb@kernel.org> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Thomas Renninger <trenn@suse.de> Acked-by: H.
