Subject: dmidecode: Only scan /dev/mem for entry point on x86
Git-commit: e12ec26e19e02281d3e7258c3aabb88a5cf5ec1d
Patch-mainline: yes
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.
This fixes support request #109697:
