#     powerpc/kvm/booke: Fix altivec related build break
#     
#     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'
#     
#     Fixes: 09f984961c137c4b ("KVM: PPC: Book3S: Add MMIO emulation for VMX instructions")
