Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `function apply_seal_endbr`, `function gen_endbr_poison`, `function __is_endbr`, `function is_endbr`, `function ibt_save`, `function ibt_restore`.
• 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.
