If this was on a powerkvm guest set-indicator should be present for

Right that does explain it. I went looking for the KVM kernel/qemu code that
implements set-indicator but couldn't find it. Presumably it's in some branch
other than the one I was looking at, or I was grepping for the wrong thing.

So I guess a printf there is probably not helpful, because it will fire always
on PowerKVM (at least at the moment).

FWIW, the PAPR mentions that the surveillance indicator may not be
implemented. In that case -3 is returned.? I double checked that on my LPAR.

One option would be to warn only if the returned value is different from
0 and -3.
