[Qemu-devel] [RESEND PATCH v9 0/4] remove icc bus/bridge

[Zhu Guihua]

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 unnecessary.

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 based on the latest master.

v9:
 -use a callback to correct reset sequence for x86
 -update apic mmio mapping

v8:
 -add a wrapper to specify reset order

v7:
 -update to register reset handler for main_system_bus when created
 -register reset handler for apic after all devices are initialized

Chen Fan (2):
  apic: map APIC's MMIO region at each CPU's address space
  cpu/apic: drop icc bus/bridge

Zhu Guihua (2):
  x86: use new method to correct reset sequence
  icc_bus: drop the unused files
