This file is part of ACPICA which is a separate project whose code is
used by the Linux kernel.  In order to make changes in the ACPICA
code, please submit a pull request to the upstream ACPICA project on
GitHub.  Once this pull request is merged, you can send a
corresponding Linux patch with a Link: tag pointing to it.  However,
it is not necessary to do so, as the changes will be automatically
included into the ACPICA code in the kernel once a new version of
ACPICA is out.
