From 91cb8860cb31ad826ff30dc39f3ed7c981139d42 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Mon, 27 Sep 2021 14:41:19 +0800 Subject: of, numa: Fetch empty NUMA node ID from distance map There is no device node for the empty NUMA node. However, the corresponding NUMA node ID and distance map is still valid in "numa-distance-map-v1" compatible device node. This fetches the NUMA node ID and distance map for these empty NUMA node from "numa-distance-map-v1" compatible device node.
