Hi Mike and Andrew, It looks like everyone is happy with this version so far. How should we merge it for linux-next? I'm happy to take it through the asm-generic tree, but linux-mm would fit at least as well. In case we go for linux-mm, feel free to add Acked-by: Arnd Bergmann for the whole series. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
