tudorl · mpe · commit b2d7ecbe3556 · 2018-04-27T16:36:03.000+10:00
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: 09f9849 ("KVM: PPC: Book3S: Add MMIO emulation for VMX instructions") Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
