   # 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
