commit 9b4416c5095c20e110c82ae602c254099b83b72f upstream.

In commit 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in C") kvm_start_guest() became idle_kvm_start_guest(). The old code allocated a stack frame on the emergency stack, but didn't use the frame to store anything, and also didn't store anything in its caller's frame.

Please drop this and the next patch.

cheers
