+What: /sys/firmware/acpi/hotplug/force_remove
+Date: Mar 2017
+Contact: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+Description:
+ Since the force_remove is inherently broken and dangerous to
+ use for some hotplugable resources like memory (because ignoring
+ the offline failure might lead to memory corruption and crashes)
+ enabling this knob is not safe and thus unsupported.
