Thank you for the series. I notice that none of these patches have a Reviewed-by nor a Tested-by from some other Intel developers.

It really helps if you can get someone other Intel kernel people to review and test your patches and then add their tags before posting a large(ish) series like this upstream.

Regards,

Hans
