Julien Thierry 95e92e45a4 KVM: arm64: pmu: Make overflow handler NMI safe ... kvm_vcpu_kick() is not NMI safe. When the overflow handler is called from NMI context, defer waking the vcpu to an irq_work queue. A vcpu can be freed while it's not running by kvm_destroy_vm(). Prevent running the irq_work for a non-existent vcpu by calling irq_work_sync() on the PMU destroy path.
