[ Upstream commit fe6de81b610e5d0b9d2231acff2de74a35482e7d ]
objtool throws the following warning: arch/powerpc/kvm/booke.o: warning: objtool: kvmppc_fill_pt_regs+0x30: unannotated intra-function call
Fix the warning by setting the value of 'nip' using the _THIS_IP_ macro, without using an assembly bl/mflr sequence to save the instruction pointer.
