I agree this should probably go through tip. I'm sure Ingo is busy
working through the merge window now too, and is not focusing on this
thread.

Anyway, this thread still has RFC in it. Send out a new patch (new
thread) with the Subject:

[PATCH -tip] introduce sys_membarrier(): process-wide memory barrier (v9))


With all Acked-by's given and state that it is ready for inclusion in
v2.6.34. (make this statement at the top of the email) It may still not
make 2.6.34, but at least it will be on its way to 2.6.25 (or 3.0
*wish*)
