Christoffer Dall f3662e3325 KVM: arm/arm64: Fix vgic init race ... [ Upstream commit 1d47191de7 ] The vgic_init function can race with kvm_arch_vcpu_create() which does not hold kvm_lock() and we therefore have no synchronization primitives to ensure we're doing the right thing. As the user is trying to initialize or run the VM while at the same time creating more VCPUs, we just have to refuse to initialize the VGIC in this case rather than silently failing with a broken VCPU.
