Maybe. But maybe it's representative... so far in this merge window,
100% of the powerpc build and runtime breakage upstream comes from stuff
that didn't get into -next before.

Some of the runtime breakage in powerpc-next comes from my own bugs,
indeed, and fortunately I caught it before I asked Linus to pull.

Ben.
