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

- Immediate include surface: `linux/init.h`, `linux/linkage.h`, `asm/lowcore.h`, `asm/asm-offsets.h`, `asm/thread_info.h`, `asm/page.h`, `asm/ptrace.h`.
- Atlas domain: Architecture Layer / arch/s390.
- Implementation status: atlas-only.
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.
