Symlinks are created at the old locations for backward compatibility and can be removed in the future [01/03]. While doing this cleanup, the old kexec and kdump sysfs entries are marked as deprecated in the existing ABI documentation [02/03]. This makes it clear that these older interfaces should no longer be used. New ABI documentation is added to describe the reorganized interfaces [03/03], so users and tools can rely on the updated layout going forward.
