+    spapr/xive: Allocate IPIs independently from the other sources
+    
+    The vCPU IPIs are now allocated in kvmppc_xive_cpu_connect() when the
+    vCPU connects to the KVM device and not when all the sources are reset
+    in kvmppc_xive_source_reset()
+    
+    This requires extra care for hotplug vCPUs and VM restore.
