From fbe63acf62f57f8e51adae602c5ce1025002d5ee Mon Sep 17 00:00:00 2001 From: Yazen Ghannam Date: Mon, 20 Mar 2017 15:26:51 -0500 Subject: EDAC, mce_amd: Use cpu_to_node() to find the node ID Using the homegrown amd_get_nb_id() to find a node ID on AMD was fine while the L3 to node mapping was 1:1. And Zen topology broke this. So let's start slowly moving away from it and use the topology interfaces instead.
