Hi,

I notice a bug report on Bugzilla [1]. Quoting from it:

> v6.5 (and at least v5.15, v5.19 and v6.4 as well) will not go to a higher power saving level than package C3.
> 
> With the inclusion of a patch that combines 3 Ubuntu commits related to VMD ASPM & LTR, package C8 is used.

See Bugzilla for the full thread.

FYI, the attached proposed fix is the same as Brett's another BZ report [2].
I include it for upstreaming.

To Brett: Would you like to submit the proper, formal patch (see
Documentation/process/submitting-patches.rst for details)?

Thanks.
