So I had a look, dreading the selecti-idle-sibling changes, and was
pleasantly surprised they're gone :-)
As is, this does indeed look like something mergable without too much

The one questino I have is, do we want default y?
The one nit I have is the Kconfig text, I'm not really sure that's
clarifying what a cluster is.
