During pci root bus hot-add, ioapic and iommu need to be parsed at first.
Using acpi_pci_driver->add to do that.
The patches need to apply to for-pci-root-bus-hotplug and for-x86-irq
and those two patches have been rebased to 3.4-rc1.
could get from
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-iommu
Thanks
