David Hildenbrand 5c0aea0e8d KVM: x86: don't hold kvm->lock in KVM_SET_GSI_ROUTING ... We needed the lock to avoid racing with creation of the irqchip on x86. As kvm_set_irq_routing() calls srcu_synchronize_expedited(), this lock might be held for a longer time. Let's introduce an arch specific callback to check if we can actually add irq routes. For x86, all we have to do is check if we have an irqchip in the kernel. We don't need kvm->lock at that point as the irqchip is marked as inititalized only when actually fully created.
