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.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• function __patch_text
• function __patch_text_early

Annotated Snippet

#ifndef _ARM_KERNEL_PATCH_H
#define _ARM_KERNEL_PATCH_H

void patch_text(void *addr, unsigned int insn);

static inline void __patch_text(void *addr, unsigned int insn)

	__patch_text_real(addr, insn, true);
}

Annotation

• Detected declarations: `function __patch_text`, `function __patch_text_early`.
• 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.
