The concept of movable memory was initially designed for hot-pluggable
memory on server-class systems, but it would now appear that this mechanism
is finding a new use in consumer-electronics devices as well. The
designated movable block patch set was first submitted
by Doug Berger in September 2022. By adding more flexibility around the
configuration and use of movable memory, this work will, it is hoped, improve how
Linux performs on resource-constrained systems.
