[ Added Linus to verify what I'm talking about ]

No, what I could do is to push the branch out to my repository on
kernel.org (I'm currently running it under my test suite), and then both
you and Ingo can pull from it.

It is based off of v3.6-rc5 and only has Josh's change in it. This way,
when Ingo pulls it into the perf/core branch, I can work against that,
and you could either pull the same branch directly from me (as you need
it to work too), or you could have Ingo pull it into the rcu branches in
tip, and you could work against that.

The trick is that the branch I push is against Linus's tree (something
that we all should be working against) and contains only the one change.
Then everyone that needs this change can just pull it directly, and git
will sort it all out without any conflicts. This is the method that
Linus was talking about at Kernel Summit.
