+ This debug facility allows ACPI AML methods to me inserted and/or
+ replaced without rebooting the system. For details refer to:
+ Documentation/acpi/method-customizing.txt.

+ NOTE: This option is security sensitive, because it allows arbitrary

+ to bypass certain security measures (e.g. if root is not allowed to
+ load additional kernel modules after boot, this feature may be used
+ to override that restriction).
