Annotation

• Immediate include surface: `asm-generic/sections.h`.
• Detected declarations: `function in_entry_text`, `function in_idmap_text`.
• Atlas domain: Architecture Layer / arch/arm.
• 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.
