Hi Taku,
You are right. acpi_pci_root.mmconf_added is used to track
whether MMCFG info is added by pci_mmconfig_insert(), and
arch_acpi_pci_root_remove() will only delete MMCFG info added by
pci_mmconfig_insert().

Hi Jiang,
Thanks, and I have another question.
What does "acpi_pci_root.mmconf_added" indicate ?
In case of non-hotpluggable hostbridges, that is, when MMCONF
is described using MCFG table, acpi_pci_root.mmconf_added is always 0.
Is "acpi_pci_root.mmconf_added" only for hotpluggable hostbridges ?
