File dmidecode-only-scan-dev-mem-for-entry-point-on-x86.patch of Package dmidecode
From: Jean Delvare <jdelvare@suse.de> Date: Mon, 26 Aug 2019 14:20:15 +0200 Subject: dmidecode: Only scan /dev/mem for entry point on x86 Git-commit: e12ec26e19e02281d3e7258c3aabb88a5cf5ec1d Patch-mainline: 3.3 x86 is the only architecture which can have a DMI entry point scanned from /dev/mem. Do not attempt it on other architectures, because not only it can't work, but it can even cause the system to reboot.
