* ehabkost/tags/x86-and-machine-pull-request: (29 commits)
migration/i386: Remove support for pre-0.12 formats
vmstatification: i386 FPReg
migration/i386: Remove old non-softfloat 64bit FP support
tests: check -numa node,cpu=props_list usecase
numa: add '-numa cpu,...' option for property based node mapping
numa: remove node_cpu bitmaps as they are no longer used
numa: use possible_cpus for not mapped CPUs check
machine: call machine init from wrapper
numa: remove no longer need numa_post_machine_init()
tests: numa: add case for QMP command query-cpus
QMP: include CpuInstanceProperties into query_cpus output output
virt-arm: get numa node mapping from possible_cpus instead of numa_get_node_for_cpu()
spapr: get numa node mapping from possible_cpus instead of numa_get_node_for_cpu()
pc: get numa node mapping from possible_cpus instead of numa_get_node_for_cpu()
numa: do default mapping based on possible_cpus instead of node_cpu bitmaps
numa: mirror cpu to node mapping in MachineState::possible_cpus
numa: add check that board supports cpu_index to node mapping
virt-arm: add node-id property to CPU
pc: add node-id property to CPU
spapr: add node-id property to sPAPR core
