Using: gcc (GCC) 4.5.0 20100610 (prerelease) The following warning is seen: drivers/acpi/processor_idle.c:83:12: warning: ‘us_to_pm_timer_ticks’ defined but not used This is because us_to_pm_timer_ticks is only used when CONFIG_ACPI_PROCFS is defined. Fix the warning by moving the function definition into the #ifdef CONFIG_ACPI_PROCFS block.
