OK, thanks!

So patches [4-6/6] appear to be cleanups and I'd prefer them to be
applied in a usual way (ie. via the upstream ACPICA).

I'd like to take the [1-3/6] as fixes for 4.9-rc3 though, but for that
I need you to tell me which mainline kernel commits are fixed by them.

IOW, what should I put into the Fixes: tags.

[In the future, if you post a regression fix, please always add a
FIxes: tag to it pointing to the commit being fixed.]
