It's rather fluffy, but it doesn't make unfounded claims about space
savings, so in that regard I'm fine with it.
[It's probably just my lack of imagination, but I still fail to see how
one could ever achieve better than the linker creating just 1
vmlinux-wide instance of "enabled", which I believe happens regardless
of whether one uses these helpers or not.]
