Annotation
- Immediate include surface: `asm/hwcap.h`, `asm/simd.h`, `linux/cpufeature.h`.
- Detected declarations: `function nh_arch`, `function nh_mod_init_arch`.
- Atlas domain: Kernel Services / lib.
- 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.
