* remotes/ehabkost/tags/x86-pull-request:
  vl: exit if a bad property value is passed to -global
  qdev: ignore GlobalProperty.errp for hotplugged devices
  machine: Add comment to abort path in machine_set_kernel_irqchip
  Revert "pc: Enforce adding CPUs contiguously and removing them in opposite order"
  pc: Init CPUState->cpu_index with index in possible_cpus[]
  qdev: Fix object reference leak in case device.realize() fails
  exec: Set cpu_index only if it's not been explictly set
  exec: Don't use cpu_index to detect if cpu_exec_init()'s been called
  exec: Reduce CONFIG_USER_ONLY ifdeffenery
