Annotation

• Immediate include surface: `asm/ftrace.h`, `linux/uaccess.h`, `linux/pgtable.h`, `asm/string.h`, `asm/page.h`, `asm/checksum.h`, `asm/mce.h`, `asm-generic/asm-prototypes.h`.
• 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.
