When I sent that to you, I was referring to these build results:

http://kisskb.ellerman.id.au/kisskb/buildresult/1307802/

which (as you say) was only a waning in the rest of the kernel but is
turned into an error by the -Werror we use when building arch/powerpc.
The warning came from commit 4765c1db84c73f775eb1822a009117cbae524e9e
("rcu-tiny: The Bloatwatch Edition, v6") in the -tip tree and fixed by
commit 5ef9b8e59c043624fb44e31439cecf7f8b4cd62a ("rcu: Clean up the
warning message about RCU not defined") the next day (in the -tip tree).
So no big problem.  Neither of these commits are upstream.

I was just filling in the role of notifying you of build problems until
Michael can automate it.
