Why This File Exists
CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
- CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
- Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
- Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

- Detected declarations: `struct insn_emulation`, `enum insn_emulation_mode`, `enum legacy_insn_status`, `function aarch32_check_condition`, `function variants`, `function swp_handler`, `function try_emulate_swp`, `function cp15barrier_handler`, `function cp15_barrier_set_hw_mode`, `function try_emulate_cp15_barrier`.
- Atlas domain: Architecture Layer / arch/arm64.
- Implementation status: integration implementation candidate.
- Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
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.
