└─> Allow ACPI methods to be inserted/replaced at run time

This debug facility allows ACPI AML methods to be 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
kernel memory to be written to by root (uid=0) users, allowing them
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).
