    Subject[PATCH] ACPI: processor_idle: delete use of NOP CPUIDLE_FLAGs
    From: Len Brown <len.brown@intel.com>

    CPUIDLE_FLAG_SHALLOW
    CPUIDLE_FLAG_BALANCED
    CPUIDLE_FLAG_DEEP
    CPUIDLE_FLAG_CHECK_BM

    were set by acpi_processor_setup_cpuidle(),
    but never used by cpuidle or by acpi_idle.
    So stop setting them.
