Browse Source 
Silence the following warnings when built with W=1:

 | CC   drivers/acpi/processor_idle.c
 |      warning: no previous prototype for 'acpi_processor_ffh_lpi_probe' [-Wmissing-prototypes]
 |		int __weak acpi_processor_ffh_lpi_probe(unsigned int cpu)
 |                         ^
 | CC   drivers/acpi/processor_idle.c
 |      warning: no previous prototype for 'acpi_processor_ffh_lpi_enter' [-Wmissing-prototypes]
 |              int __weak acpi_processor_ffh_lpi_enter(struct acpi_lpi_state *lpi)
 |                         ^
