The branch stable/14 has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=148222e3a09965a7d8af72d00ee4584a0df16ca7 commit 148222e3a09965a7d8af72d00ee4584a0df16ca7 Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2023-10-26 10:21:57 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2024-02-19 13:13:30 +0000 arm64: Use a hwcap ID rather than pointer To allow for a different Linux hwcap value store the hwcap ID rather than a pointer to elf{32,}_hwcap{2,}. This will be needed when creating a different view of the ID registers for FreeBSD and Linux.
