As a general rule, ACPICA changes should be submitted as pull requests to the upstream ACPICA project on GitHub, from where they are backported (semi-automatically) to Linux. However, if an upstream ACPICA pull request has been submitted, a corresponding Linux patch can be posted with a Link: tag pointing to that pull request.
