Bug Description
To enable NVME APST (autonomous power state transitions) to conserve NVME power consumption, this commit is required:
commit 034e7906211c18c
Author: Andrew Lutomirski <email address hidden>
Date: Tue Nov 29 17:11:52 2016 -0800
PM / QoS: Export dev_pm_
nvme wants a module parameter that overrides the default latency
tolerance. This makes it easy for nvme to reflect that default in
sysfs.
