next-20211210 ( commit ea922272cbe547) powerpc build fails due to following error:

arch/powerpc/kvm/book3s_hv.c: In function 'kvmhv_run_single_vcpu':
arch/powerpc/kvm/book3s_hv.c:4591:27: error: 'struct kvm_vcpu' has no member named 'wait'
   prepare_to_rcuwait(&vcpu->wait);
                           ^~
arch/powerpc/kvm/book3s_hv.c:4608:23: error: 'struct kvm_vcpu' has no member named 'wait'
   finish_rcuwait(&vcpu->wait);
                       ^~ 

commit 510958e997217: KVM: Force PPC to define its own rcuwait object 
introduced the error. 

Thanks
