To some extent, here, the issue is on Linus side and it's up to him (Hey
Linus ! still listening ?) to maybe be more proactive at giving an ack
or nack so that we can get a chance to do that final pass of ironing out
the mechanical bugs before we hit the main tree.

Let me add a little bit more background to my reasoning here and why I
think having this integration testing step is so valuable...

It all boils down to bisection and having a bisectable tree.

I think you are way too concentrated on this particular incident, 
and you are generalizing it into something that is not so in 
practice.

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.

Cheers,
Ben.
