This patch series makes it possible to use Rust together with the shadow call stack sanitizer. The first patch is intended to be backported to ensure that people don't try to use SCS with Rust on older kernel versions. The second patch makes it possible to use Rust with the shadow call stack sanitizer.
The second patch in this series doesn't make sense without [1], though it doesn't break the build if [1] is missing.
