| Subject: powerpc/kvm/booke: Fix altivec related build break |
| |
| From: Laurentiu Tudor <laurentiu.tudor@nxp.com> |

| [ Upstream commit b2d7ecbe355698010a6b7a15eb179e09eb3d6a34 ] |
| |
| Add missing "altivec unavailable" interrupt injection helper |
| thus fixing the linker error below: |
| |
| arch/powerpc/kvm/emulate_loadstore.o: In function `kvmppc_check_altivec_disabled': |
| arch/powerpc/kvm/emulate_loadstore.c: undefined reference to `.kvmppc_core_queue_vec_unavail' |
