Just noticed that this removes the ACPICA header dependency problem
that Rafael pointed out.  This also applies (with minor offsets) to
v6.9-rc1, so it's not very stale.  We're almost to the v6.9 final
release, so when v6.10-rc1 is tagged, can you rebase to that and
repost this?

I assume you have a platform that uses this.  It would be good to
mention that in the commit log of patches 1 and 3 so we have some idea
of where it's useful and where changes need to be tested.
