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 <arnd@xxxxxxxx> for the whole series.
