From: Haibin Wang <wanghaibin.wang@huawei.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 91021a6c8ffdc55804dab5acdfc7de4f278b9ac3 upstream.
When dispatch SGI(mode == 0), that is the vcpu of VM should send sgi to the cpu which the target_cpus list. So, there must add the "break" to branch of case 0.
