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.

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

  -add a wrapper to specify reset order

  -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
