Sorry this explanation is long winded, but this is a messy situation.
In Linux, there isn't a very consistent policy about userspace kernel
header inclusion. On a typical Linux system, you're likely to find
kernel headers in three places.
glibc headers

Can you clarify this? I can't find any version of usbdevice_fs.h that

Right, but if you e.g. try to build a newer qemu-kvm on F10, you
currently need newer kvm kernel headers - IMHO, we should use #ifdef to
allow newer qemu-kvm build with older kvm headers.
I think the kvm and virtio headers should just be shipped

I don't see the need to copy all the core headers. These should have
been working for ages, and hardly ever see changes that are relevant
to kvm.
If we want to use virtio_*.h instead of duplicating the copies as we
are now, then we need all of the core headers

qemu provides virtio, it doesn't consume it. We can merge the virtio
headers and remove the linuxisms.
Yeah. virtio is a one the (virtual) wire protocol, not a kernel ABI in
the tradition sense. qemu should have it's own defintion.

In general a distro provides kernel headers matched to the running
kernel. For example F10 provides
kernel-headers-2.6.27.21-170.2.56.fc10.x86_64 to go along with
kernel-2.6.27.21-170.2.56.fc10.x86_64. So a user
