RE: [PATCH] Enable ACPI_ADR_SPACE_PCI_CONFIG in acpi_gbl_default_address_spaces only when ACPI_PCI_CONFIGURED is defined

[Moore, Robert]

Well, I don't like the fact that PCI_CONFIGURED would have to be defined by each current host:

> +#ifdef ACPI_PCI_CONFIGURED

I would rather the logic be reversed:

> +#ifdef ACPI_PCI_NOT_CONFIGURED

This looks good to me. Bob, do you have any comments?
