[Bug 1441334] [NEW] PCI: Don't clear ASPM bits when the FADT declares it's unsupported

 

Public bug reported:

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>.

** Affects: linux (Ubuntu)
