Subject: ACPI: processor_idle: delete use of NOP CPUIDLE_FLAGs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0aae9f923bcc476a8e4725dd3ac37547b9816ee5;p=linux-beck.git

ACPI: processor_idle: delete use of NOP CPUIDLE_FLAGs

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.
