Igor Mammedov 79e0793614 numa: cpu: calculate/set default node-ids after all -numa CLI options are parsed ... Calculating default node-ids for CPUs in possible_cpu_arch_ids() is rather fragile since defaults calculation uses nb_numa_nodes but callback might be potentially called early before all -numa CLI options are parsed, which would lead to cpus assigned only upto nb_numa_nodes at the time possible_cpu_arch_ids() is called. Issue was introduced by (7c88e65 numa: mirror cpu to node mapping in MachineState::possible_cpus) and for example CLI: -smp 4 -numa node,cpus=0 -numa node would set props.node-id in possible_cpus array for every non explicitly mapped CPU to the first node. Issue is not visible to guest nor to mgmt interface due to 1) implictly mapped cpus are forced to the first node in case of partial mapping 2) in case of default mapping possible_cpu_arch_ids() is called after all -numa options are parsed (resulting in correct mapping). However it's fragile to rely on late execution of possible_cpu_arch_ids(), therefore add machine specific callback that returns node-id for CPU and use it to calculate/ set defaults at machine_numa_finish_init() time when all -numa options are parsed.
