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@arndb.de>

for the whole series.
