Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• linux/types.h
• pi.h

Detected Declarations

Annotated Snippet

if ((*relr & 1) == 0) {
			place = (u64 *)(*relr + offset);
			*place++ += offset;
		} else {
			for (u64 *p = place, r = *relr >> 1; r; p++, r >>= 1)
				if (r & 1)
					*p += offset;
			place += 63;
		}
	}
}

Annotation

• Immediate include surface: `linux/elf.h`, `linux/init.h`, `linux/types.h`, `pi.h`.
• Detected declarations: `function relocate_kernel`.
• Atlas domain: Architecture Layer / arch/arm64.
• 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.
