From eaa3a1d46cfdbf1af50311e7a22f5d38c0418b56 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 18 May 2018 13:13:31 +0200 Subject: EDAC, ghes: Make platform-based whitelisting x86-only ARM machines all have DMI tables so if they request hw error reporting through GHES, then the driver should be able to detect DIMMs and report errors successfully (famous last words :)). Make the platform-based list x86-specific so that ghes_edac can load on ARM.
