Rafael, what happened to this? From the github acpica discussion is looks a lot like there was no real progress. And drivers/acpi/acpica/evevent.c in next looks unchanged; and from searching for ACPI_EVENT_PCIE_WAKE on lore it also looks like neither the fix nor a revert was posted. But I might be missing something.
/me still hopes we can get this fixed somehow before Linus releases 6.3
