+Description:
+ There are separate hotplug profiles for different classes of
+ devices supported by ACPI, such as containers, memory modules,
+ processors, PCI root bridges etc. A hotplug profile for a given
+ class of devices is a collection of settings defining the way
+ that class of devices will be handled by the ACPI core hotplug
+ code. Those profiles are represented in sysfs as subdirectories
+ of /sys/firmware/acpi/hotplug/.
+
+ The following setting is available to user space for each
+ hotplug profile:
+
+ enabled: If set, the ACPI core will handle notifications of
+ hotplug events associated with the given class of
+ devices and will allow those devices to be ejected with
+ the help of the _EJ0 control method. Unsetting it
+ effectively disables hotplug for the correspoinding
+ class of devices.
+
+ The value of the above attribute is an integer number: 1 (set)
+ or 0 (unset). Attempts to write any other values to it will
+ cause -EINVAL to be returned.
