The original kvm_virtio.h code was added in 2008

virtio: clarify that ABI is usable by any implementations
We want others to implement and use virtio, so it makes sense to BSD
license the non-__KERNEL__ parts of the headers to make this crystal
clear.
and it seems that it missed arch/include/uapi/asm/kvm_virtio.h
arch/include/uapi/asm/virtio_ccw.h probably just copied what
kvm_virtio.h had in 2013.
So its somewhat fair to assume that both files should be BSD, but they are not
according to the licence statement.
Gregs SPDX change just changed the GPL text in the header files to a SPDX
statement. Now Michael wants to change this to BSD as it probably was intended
but not written down. Sigh.
