Patch Review

Good coverage of alignment, byte-order, window repositioning, and error rejection. The misalignment rejection test (Test 5) is valuable for verifying MMIO access safety.

---

**Summary of actionable items:**
- Fix mbox patch ordering to match the cover letter's logical sequence
- Consider squashing patches 1+2
- `VirtualAddress::level_index()` L5 returning `l4_index()` needs clarification/verification
- `AperturePte::from(u8)` catch-all silently defaulting to `VideoMemory` is risky
- `Cell<BootParams>` pattern in `Gpu::new()` is fragile; consider refactoring
- `ensure_pte_path()` per-VFN O(N*depth) walk could be optimized
- `execute_map()` drains all prepared pages -- document serialization constraint
- `FbLayout::set_usable_vram()` should error on overflow rather than saturating
