Right, and in that case you don't need an UE counter because it won't go higher than 1, would it?
What my thought is, is that if the system panics on UE unconditionally anyway (either by sw or a hw method), then you don't need to enable panic_on_ue in edac because it does so anyway, and, as a result, you don't need UE counters at all. So, in that case, you could "state" in the driver that you don't want to init the UE counters because you're not going to use them, no?
