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 and
'[PATCH v3] i386: keep cpu_model field in MachineState uptodate'
https://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg03375.html
which has been reviewed but not been merged.
v11:
-improve commit messages
-split per CPU AS change into a separate patch
v10:
-improve commit messages in patch 1 and 2
-make the check of cpu->cpu_as_root simplier
v9:
-use a callback to correct reset sequence for x86
-update apic mmio mapping
Chen Fan (2):
apic: move APIC's MMIO region mapping into APIC
cpu/apic: drop icc bus/bridge
Zhu Guihua (3):
apic: use per CPU AS to map APIC MMIO for TCG
x86: use new method to correct reset sequence
icc_bus: drop the unused files
