Great, let's try it then.  For this series (well, for v2 of this series)
only patches 1-4 would be considered infrastructure.  They were sent
before soft freeze, would they be acceptable for 2.6?

In general I would send "safe" patches as [PATCH mm/nn] and everything
else as [PATCH multiqueue mm/nn] or similar, but in either case I'd be
seeking formal maintainer review as soon as I send them.
