Why This File Exists
CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

Annotation
- Immediate include surface: `linux/string.h`, `linux/printk.h`, `linux/cache.h`, `linux/cpufeature.h`, `asm/sev-common.h`.
- Detected declarations: `function init_sev_config`.
- Atlas domain: Architecture Layer / arch/x86.
- Implementation status: source implementation candidate.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
