Merge branch 'topic/ppc-kvm' into next

Merge Nicks commit to rework the KVM thread management, shared with the
KVM tree via the ppc-kvm topic branch.

KVM: PPC: Book3S HV: POWER9 does not require secondary thread management

POWER9 CPUs have independent MMU contexts per thread, so KVM does not
need to quiesce secondary threads, so the hwthread_req/hwthread_state
protocol does not have to be used. So patch it away on POWER9, and patch
away the branch from the Linux idle wakeup to kvm_start_guest that is
never used.

Add a warning and error out of kvmppc_grab_hwthread in case it is ever
called on POWER9.

This avoids a hwsync in the idle wakeup path on POWER9.

Merge tag 'sound-4.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-rt5677

sound fixes for 4.13-rc7

We're keeping in a good shape, this batch contains just a few small
fixes (a regression fix for ASoC rt5677 codec, NULL dereference and
error-path fixes in firewire, and a corner-case ioctl error fix for
user TLV), as well as usual quirks for USB-audio and HD-audio.

There's a non-trivial dependency between some commits we want to put in
