In order to modify the ACPICA code in the Linux kernel, you need to
submit a corresponding pull request to the upstream ACPICA project on
GitHub.  Once that pull request has been merged, please send the Linux
patch with a Link: tag pointing to the upstream ACPICA pull request
corresponding to it.

Thanks!
