Release DMA mappings when BIOs complete
...
BIO completion previously did not immediately drop the associated DMA mapping,
which left a short window where the same page could be submitted again before
the old mapping was released. That could lead to duplicate mappings for the
same physical range and trigger a failure in DMA mapping.
Release the mapping as soon as the BIO completes. This avoids the duplicate-
mapping window and better matches the lifecycle of a finished BIO.

Remove all manually-written log prefixes
...
Remove bracket-style prefixes ([IOAPIC], [sys_getpid], [Task entry],

provides (VirtIO Input:, IOMMU, PCI device, etc.) across the kernel
syscalls, virtio, PCI, IOMMU, IRQ, UART, ACPI, timer, mlsdisk, input,
and rootfs subsystems.

Enforce `alphabetical-attrs` guideline across the codebase
...
Sort all non-derive outer attributes alphabetically by name,
place `#[derive(...)]` last (before any derive helper attributes
like `#[serde(...)]` and `#[clap(...)]`), and sort traits inside
`#[derive(...)]` alphabetically. This covers 329 files with 704
line changes (all pure reordering, no semantic changes).
Key patterns normalized:
- `#[cfg(...)]` comes first (c), then other attrs alphabetically
- `#[repr(...)]` stays before `#[derive(...)]` (derive is always last)
- `#[padding_struct]` and `#[pod_union]` precede `#[derive(...)]`
- Derive helper attrs like `#[serde(...)]` remain after `#[derive(...)]`
- Derive traits like `Debug, Clone, Copy` become `Clone, Copy, Debug`
- The common set `{Debug, Clone, Copy, Pod, Default}` (59 uses,
12 prior orderings) is now uniformly `Clone, Copy, Debug, Default, Pod`
