This is deliberately not a Kconfig option because it is a terrible idea
to do this in production and making it either selectable or the default
is an invitation to abuse.  We want to place a barrier here so that
users know that this is something that they have taken a decision to
enable, not something that is in any way supported (this is also why we
taint the kernel when people do write).
