Linux 4.6 rc6

Things continue to be fairly calm, although I'm pretty sure I'll still
do an rc7 in this series.

There's nothing particularly scary in here - there's a fix for a
long-standing infiniband interface problem, but since you actually
have to have the hardware for that, it's not like that is going to
affect all that many people, and the workaround was pretty
straightforward. The bulk of the rest is really just the normal random
noise. Drivers (sound, gpu, ethernet being the bulk of it),
architectures (arm, s390, x86), networking is the bulk of it.

Shortlog appended for your edification,
