    Subject[PATCH 3.12 129/182] KVM: ARM: vgic: Fix sgi dispatch problem
    Date
    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.
