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/export.h`, `linux/string.h`, `linux/delay.h`, `linux/in6.h`, `linux/syscalls.h`, `asm/checksum.h`, `asm/cacheflush.h`, `linux/io.h`.
- Detected declarations: `export _mcount`, `export __copy_tofrom_user`, `export memcpy`, `export memmove`, `export mbc`, `export __divsi3`, `export __modsi3`, `export __mulsi3`, `export __udivsi3`, `export __umodsi3`.
- Atlas domain: Architecture Layer / arch/microblaze.
- 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.
