[PATCH 0/2] introduce PM QoS interface

Subject: [PATCH 0/2] introduce PM QoS interface                           

The system-wide CPU latency QoS limit has a positive impact on the idle
state selection in cpuidle governor.

Linux creates a cpu_dma_latency device under '/dev' directory to obtain the
CPU latency QoS limit on system and send the QoS request for userspace.
Please see the PM QoS framework in the following link:
https://docs.kernel.org/power/pm_qos_interface.html?highlight=qos
This feature is supported by kernel-v2.6.25.

The deeper the idle state, the lower the power consumption, but the longer
the resume time. Some service are delay sensitive and very except the low
resume time, like interrupt packet receiving mode.

So this series introduce PM QoS interface.
