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.
- Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
- Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

- Immediate include surface: `linux/init.h`, `linux/kthread.h`, `linux/hrtimer.h`, `linux/fs.h`, `linux/debugfs.h`, `linux/export.h`, `linux/spinlock.h`, `asm/debug.h`.
- Detected declarations: `struct spin_multi_state`, `struct spin_multi_per_thread`, `function ss_get`, `function multi_other`, `function multi_get`, `function spinlock_test`, `module init spinlock_test`.
- Atlas domain: Architecture Layer / arch/mips.
- Implementation status: integration implementation candidate.
- Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
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.
