As I was building with this patch I (re-)discovered that since 2013 it depends on BROKEN (commit 76fc253723add). Despite commit message there saying that it's a temporary patch it seems to me by now that it's more than that.

And clearly noone tried to build these files since at least 2015 because memhotplug file doesn't compile due to commit cfafae940381207.

While this is easily fixable the question is whether we want to keep these files. Obviously noone cares about this functionality.
