This ends up calling DO_KVM macro twice with same parameters which
generates the following compile error:
arch/powerpc/mm/tlb_low_64e.S:307: Error: symbol `kvmppc_resume_14_0x01B' is
already defined
arch/powerpc/mm/tlb_low_64e.S:319: Error: symbol `kvmppc_resume_13_0x01B' is
already defined
We can live with it if we patch DO_KVM like this:
diff --git a/arch/powerpc/include/asm/kvm_booke_hv_asm.h
b/arch/powerpc/include/asm/kvm_booke_hv_asm.h
