Note, there is no known functional issue with the __exit annotation, the above is merely justification for its removal. The real motivation is to be able to annotate vmx_x86_ops and svm_x86_ops with __initdata, which makes objtool complain because objtool doesn't understand that the vendor specific __initdata is being copied by value to a non-__initdata instance.
