#     powerpc/numa: Online a node if PHB is attached.
#     
#     In the current design, a numa-node is made online only if that node is
#     attached to cpu/memory. With this design, if any PCI/IO device is found
#     to be attached to a numa-node which is not online then the numa-node
#     id of the corresponding PCI/IO device is set to NUMA_NO_NODE(-1). This
#     design may negatively impact the performance of PCIe device if the
#     numa-node assigned to PCIe device is -1 because in such case we may not
#     be able to accurately calculate the distance between two nodes.
#     
#     The multi-controller NVMe PCIe disk has an issue with calculating the
#     node distance if the PCIe NVMe controller is attached to a PCI host
#     bridge which has numa-node id value set to NUMA_NO_NODE. This patch
#     helps fix this ensuring that a cpu/memory less numa node is made online
#     if it's attached to PCI host bridge.
