Following the legacy smp check rules, also add the module_id validity into x86_cpu_pre_plug(). Tested-by: Yongwei Ma Co-developed-by: Zhuocheng Ding Signed-off-by: Zhuocheng Ding Signed-off-by: Zhao Liu --- Changes since v7: * Introduced module_id instead of cluster_id. * Dropped Michael/Babu's ACKed/Tested tags since the code change. * Re-added Yongwei's Tested tag For his re-testing. Changes since v6: * Updated the comment when check cluster-id. Since there's no v8.2, the cluster-id support should at least start from v9.0. Changes since v5: * Updated the comment when check cluster-id. Since current QEMU is v8.2, the cluster-id support should at least start from v8.3. Changes since v3: * Used the imperative in the commit message.
