From: Arnd Bergmann <arnd@xxxxxxxx>
The cpufreq code can be in a loadable module, so the architecture support
for it has to be exported:
ERROR: modpost: "acpi_arch_thermal_cpufreq_pctg" [drivers/acpi/processor.ko] undefined!
Fixes: 310293a2b941 ("ACPI: processor: reduce CPUFREQ thermal reduction pctg for Tegra241")
