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.
- Touches IRQ or DMA behavior; this matters for the representative real-device path.
Dependency Surface
linux/linkage.hlinux/init.hasm/asm-offsets.hasm/coldfire.hasm/mcfsim.hasm/mcfmmu.hasm/thread_info.h
Detected Declarations
- No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

/*****************************************************************************/Annotation
- Immediate include surface: `linux/linkage.h`, `linux/init.h`, `asm/asm-offsets.h`, `asm/coldfire.h`, `asm/mcfsim.h`, `asm/mcfmmu.h`, `asm/thread_info.h`.
- Atlas domain: Architecture Layer / arch/m68k.
- Implementation status: atlas-only.
- IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.
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.
