Description of changes: Cherry-picking the changes from #3300 onto the 1.14.x branch. These changes cherry-pick the software mitigation for CVE-2023-20593 ("Zenbleed") from the latest upstream stable kernel releases (second-level cherry-picking 🍒). Note that I didn't cherry-pick the fix for the 6.1 kernel series, since it wasn't released on 1.14.0 yet.
Testing done:
Built and boot-tested the aws-k8s-1.23 (kernel 5.10) and aws-k8s-1.24 (kernel 5.15) variants for x86_64.
