...ch down while reading it.

It might help with the lunch, but it still gives a slight queasiness.
No ideas for a better version, though.

[PATCH v2 00/24] virtio: config space endian-ness cleanup
Config space endian-ness is currently a mess: fields are
not tagged with the correct endian-ness so it's easy
to make mistakes like instanciating config space in
native endian-ness.
The following patches adding sparse tagging are currently in my tree.
Lightly tested.
As a follow-up, I plan to add new APIs that handle modern config space
in a more efficient way (bypassing the version check).
