* remotes/ehabkost/tags/x86-and-machine-pull-request:
  scripts: Test script to look for -device crashes
  qemu.py: Add QEMUMachine.exitcode() method
  qemu.py: Don't set _popen=None on error/shutdown
  spapr: cleanup spapr_fixup_cpu_numa_dt() usage
  numa: move numa_node from CPUState into target specific classes
  numa: make hmp 'info numa' fetch numa nodes from qmp_query_cpus() result
  numa: make sure that all cpus have has_node_id set if numa is enabled
  numa: move default mapping init to machine
  numa: consolidate cpu_preplug fixups/checks for pc/arm/spapr
  pc: Use "min-[x]level" on compat_props
