This patch depends on kernel-specific ACPICA configuration, can I submit
it to ACPICA
projects?

ACPI core subsystem initialization will fail when Kernel disabled PCI but
ACPI tables still have PCI config address spaces.
Enable ACPI_ADR_SPACE_PCI_CONFIG in acpi_gbl_default_address_spaces
only when ACPI_PCI_CONFIGURED is defined.

As an ACPICA change, this should first be submitted (as a pull
request) to the upstream ACPICA project on GitHub.
Having done that, please resubmit the patch with a Link tag pointing
to the corresponding upstream pull request.
Thanks!
