In drivers/idle/Kconfig, we see: Cpuidle Driver for Intel Processors (INTEL_IDLE) [N/m/y/?] (NEW) ? CONFIG_INTEL_IDLE: Enable intel_idle, a cpuidle driver that includes knowledge of native Intel hardware idle features. The acpi_idle driver can be configured at the same time, in order to handle processors intel_idle does not support. I think we wanted a s/acpi_idle/processor_idle/ there?
