Bug description:
  Matthew Garrett developed a patch to make Linux's ASPM support match
  reality. Please backport this to Ubuntu's 3.13, 3.16 and 3.19 kernels.

  This should offer power savings and would match Windows behavior.

  Please see the submission at <https://lkml.org/lkml/2015/4/7/781>.
