Besides that fact that as you correctly states these are not a UAPI at
all, qemu and bootloades are not specific to Linux and can't require a
specific kernel version. So the same thing we do for file system
formats or network protocols applies here: just copy the damn header.
And as stated above any reasonably portable userspace needs to have a
copy anyway.
If it is just as a "master copy" it can live in drivers/virtio/, just
like we do for other formats.
