# HEAD: f69ca629d89d65737537e05308ac531f7bb07d5c x86/cpu: Refactor sync_core() for readability

Misc changes:

- Prepare for Intel's new SERIALIZE instruction
- Enable split-lock debugging on more CPUs
- Add more Intel CPU models
- Optimize stack canary initialization a bit
- Simplify the Spectre logic a bit
