My understanding of the issue tells me this is a correct patch.

(AFAIU, it would help to "just" load age with load_acquire, if only
load_acquire was correctly implemented on PPC, doing the full-blown
fence to ensure sequential consistency. The same effect is gained with
the explicit barrier in this patch).
