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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/cpumask.h
• linux/irqreturn.h
• linux/threads.h

Detected Declarations

• function __cpu_die

Annotated Snippet

static inline void __cpu_die(unsigned int cpu) { }

#endif /* CONFIG_SMP */

#endif /* __ASM_CSKY_SMP_H */

Annotation

• Immediate include surface: `linux/cpumask.h`, `linux/irqreturn.h`, `linux/threads.h`.
• Detected declarations: `function __cpu_die`.
• Atlas domain: Architecture Layer / arch/csky.
• 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.
