From: Haibin Wang <wanghaibin.wang@xxxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us 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.
