This looks good to me.  I merged b3a72384fe29 so maybe it would make
sense for me to merge this follow-up as well.  I put it on my
for-linus branch for v4.4.

If you'd rather merge it via an ARM tree, here's my ack:

If you want me to merge it, an ARM ack would be nice.  If you want to
merge it, let me know and I'll drop it from my tree.
