* afaerber/qom-cpu:
  target-cris: Override do_interrupt for pre-v32 CPU cores
  qdev: Set device's parent before calling realize() down inheritance chain
  cpu: Pass CPUState to *cpu_synchronize_post*()
  target-i386: Split out CPU creation and features parsing
  target-i386/cpu.c: Coding style fixes
  ioapic: Replace FROM_SYSBUS() with QOM type cast
  kvmvapic: Replace FROM_SYSBUS() with QOM type cast
  target-i386: Split APIC creation from initialization in x86_cpu_realizefn()
  target-i386: Consolidate error propagation in x86_cpu_realizefn()
  qdev: Add qdev property for bool type
  target-i386: Improve -cpu ? features output
  target-i386: Fix including "host" in -cpu ? output
