Subject: [PATCH] Fix early panic on amd64 due to typo in supported CPU section

Do not crash when enumerating supported CPU architectures

SECURITY_INIT somehow ended up in x86_cpu_dev.init section. That caused printk
in code which prints supported architectures to hit #GP due to non-canonical
address being used.
