It is difficult to be certain, but I suspect that LINUX_VERSION_CODE is
not being defined.  That would result in the compiler seeing something
like this after the preprocessor runs:

guest_id = generate_guest_id(0, , 0);

That would be consistent with the error message.  Apart from that, I
don't have any idea.
