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.

Annotation
- Immediate include surface: `linux/module.h`, `os.h`.
- Detected declarations: `export um_get_signals`, `export um_set_signals`, `export os_stat_fd`, `export os_stat_file`, `export os_access`, `export os_set_exec_close`, `export os_getpid`, `export os_open_file`, `export os_read_file`, `export os_write_file`.
- Atlas domain: Architecture Layer / arch/um.
- Implementation status: integration 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.
