[Qemu-devel] [PATCH v5 0/4] remove icc bus/bridge

ICC Bus was used for providing a hotpluggable bus for APIC and CPU,
but now we use HotplugHandler to make hotplug. So ICC Bus is

This code has passed the new pc-cpu-test.
And I have tested with kvm along with kernel_irqchip=on/off,
it works fine.

This patch series is rebased on Eduardo's x86 tree.

 -convert DEVICE() casts to C casts
 -use a local variable instead of doing the cast inline twice
 -drop to set cpu's parent bus
 -rename patch 3's subject
 -fix a bug about setting cpu's apic base

 -add wrapper to get root memory region from address space
 -set cpu apic base's default value in x86_cpu_apic_create()
 -drop NULL check for cpu apic_state
 -put drop of the unused files about icc_bus into a seprate patch
 -put DEVICE() casts into a seprate patch

 -replace init apic by object_new()
 -add reset apic at the time of CPU reset

Chen Fan (2):
  apic: move apic mmio register to each apic realizefn
  cpu/apic: drop icc bus/bridge

Zhu Guihua (2):
  apic: convert ->busdev.qdev casts to C casts
  icc_bus: drop the unused files
