linux-next: manual merge of the kvm tree with the powerpc-merge-mpe tree

Hi all,

Today's linux-next merge of the kvm tree got a conflict in
arch/powerpc/kvm/book3s_hv_rm_mmu.c between commit dac565706791 ("KVM:
PPC: Remove page table walk helpers") from the powerpc-merge-mpe tree
and commit a4bd6eb07ca7 ("KVM: PPC: Book3S HV: Add helpers for
lock/unlock hpte") from the kvm tree.

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