This is intended for use by LKMs; malloc types included in modules
statically-linked into the kernel are automatically registered with

.Fn MALLOC_JUSTDEFINE_LIMIT .
Apart from not automatically registering to the kernel a boot time,
these functions are equivalent to their counterparts.
They can be used when a separate LKM codepath for initialization is
not desired.
