ACPICA changes require (at least) a pull request to be submitted to
the upstream ACPICA project on GitHub from where the changes get pulled
into the kernel along with other changes.

If such a pull request is already created, please resend the Linux patch
with a link pointing to that pull request to inform the maintainer about
the same so that it helps in the review of the patches here.

I will submit the pull request to acpiaca and send the link when I send
v2 of this series.
