Except ARM64 iort, numa_node is actually also applicable to x86 and other
architectures through general
acpi_create_platform_device() API:

Some platform devices like ARM SMMU are memory-mapped and populated by
ACPI/IORT.
In this case, NUMA topology of those platform devices are exported by firmware
as
well. Software might care about the numa_node of those devices in order to
achieve
NUMA locality.
This patch will show the numa_node
