Subject: [PATCH 10/18] dmidecode: Only scan /dev/mem for entry point on x86
|
|
|
|
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:
