The branch stable/13 has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=b7c23efd7428256f69ccfd65a9c5e9f50585bf66 commit b7c23efd7428256f69ccfd65a9c5e9f50585bf66 Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2021-10-12 11:39:14 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2021-12-14 10:58:01 +0000 Stop reading the arm64 domain when it's known There is no need to read the domain on arm64 when there is only one in the ACPI tables. This can also happen when the table is missing as it is unneeded.
