Merge remote-tracking branch 'afaerber/qom-cpu' into staging

# By Andreas Färber (16) and Igor Mammedov (1)
# Via Andreas Färber
* afaerber/qom-cpu:
  target-lm32: Update VMStateDescription to LM32CPU
  target-arm: Override do_interrupt for ARMv7-M profile
  cpu: Replace do_interrupt() by CPUClass::do_interrupt method
  cpu: Pass CPUState to cpu_interrupt()
  exec: Pass CPUState to cpu_reset_interrupt()
  cpu: Move halted and interrupt_request fields to CPUState
  target-cris/helper.c: Update Coding Style
  target-i386: Update VMStateDescription to X86CPU
  cpu: Introduce cpu_class_set_vmsd()
  cpu: Register VMStateDescription through CPUState
  stubs: Add a vmstate_dummy struct for CONFIG_USER_ONLY
  vmstate: Make vmstate_register() static inline
  target-sh4: Move PVR/PRR/CVR into SuperHCPUClass
  target-sh4: Introduce SuperHCPU subclasses
  cpus: Replace open-coded CPU loop in qmp_memsave() with qemu_get_cpu()
  monitor: Use qemu_get_cpu() in monitor_set_cpu()
  cpu: Fix qemu_get_cpu() to return NULL if CPU not found
