Subject: linux-next: manual merge of the kvm-ppc tree with the tip tree

Hi Alexander,

Today's linux-next merge of the kvm-ppc tree got a conflict in:

  arch/powerpc/kvm/book3s_hv.c

between commit:

  c56dadf39761 ("sched/preempt, powerpc, kvm: Use need_resched() instead of should_resched()")

from the tip tree and commit:

  ec2571650826 ("KVM: PPC: Book3S HV: Make use of unused threads when running guests")

from the kvm-ppc tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
