This causes build errors when CONFIG_ACPI isn't enabled since both acpi_pci_{add,remove}_bus() aren't defined in such a configuration: arch/x86/pci/common.c: In function 'pcibios_add_bus': arch/x86/pci/common.c:176:2: error: implicit declaration of function 'acpi_pci_add_bus' arch/x86/pci/common.c: In function 'pcibios_remove_bus': arch/x86/pci/common.c:181:2: error: implicit declaration of function 'acpi_pci_remove_bus' -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
