One problem with keeping things like this in -mm (or other non-Linus tree) is that they bit-rot quickly, and become a pain to apply, especially if they are perpetually on top of other changes in -mm. I looked at trying these patches on Linus' tree when Sasha posted them, but lost motivation when I realized they needed other bits of -mm too. It may be that after Andrews 3.18+ mega-merge things would be simpler, but I have a feeling it wouldn't be long before the situation would arise again.
