This patch series is v3 of a previous posting: v2 -> v3 - Dropped generic approach # It was not consistent between ACPI and DT and not reusable on x86/IA64 - Trimmed the series to one patch ARM64 specific, three-line patch fixes the issue - Rebased against v4.12-rc2 - Dropped RFC/RFT tag v2: https://lkml.org/lkml/2017/5/15/433 v1 -> v2: - Added missing call to acpi_pci_bus_find_numa_node() - Rebased against v4.12-rc1 v1: https://lkml.org/lkml/2017/4/26/211 --- Original Cover Letter -- On the ARM64 architecture, the arch specific PCI pcibus_to_node() callback can be triggered on struct pci_bus.sysdata structures that carry host bridge specific data through different structures layout (ie sysdata pointer points at different structs for different host bridges), therefore it is not possible to have a unified pcibus_to_node() implementation. Given that the device NUMA node is a property of the struct pci_bus (and its associated struct device), move the struct pci_bus node assignment to generic PCI code, where according to the platform firmware the NUMA node for the device backing the struct pci_bus is retrieved and propagated through the PCI bus hierarchy.
