ACPICA was updated recently. It now contains the new AcpiWalkNamespace()
interface.

After thinking about this, maintaining the parent-child relationship is
definitely the way to proceed. This information is also needed for other
things. I would personally take one step forward by eliminating the local
data structures in "acpi_pci.c" (or the file altogether), and move them to
"struct acpi_devnode" instead.
