Hi,

can we consider pulling in Mika's changes again for this merge window,
they fix a
pretty serious power management regression since we started
advertising Windows 2013
ACPI compat, as lots of dual GPU laptops can no longer switch off
their secondary GPUs.

I know they had an issue, but Mika seems to have fixed it promptly,
and those patches
aren't going to get much more testing out of tree.

Dave.
