+ * KVM_X86_OP() and KVM_X86_OP_OPTIONAL() are used to help generate
+ * both DECLARE/DEFINE_STATIC_CALL() invocations and
+ * "static_call_update()" calls.
+ *
+ * KVM_X86_OP_OPTIONAL() can be used for those functions that can have
+ * a NULL definition, for example if "static_call_cond()" will be used
+ * at the call sites.  KVM_X86_OP_OPTIONAL_RET0() can be used likewise
+ * to make a definition optional, but in this case the default will
+ * be __static_call_return0.
