[PATCH v3 0/1] ARM64/PCI: ACPI NUMA node set-up

[lorenzo.pieralisi@arm.com (Lorenzo Pieralisi)]

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.
