So I tried to be more discriminate but in the end, I had to give up, the most recent ID we have in the driver seems to be Cap Verde/Pitcairn, which isn't fixed. So either we are missing IDs or the new cards use the same ID. I think the consequences of being over-zealous here are nil on what matters, ie, x86. AFAIK, x86 always uses 32-bit addresses for MSIs anyway, so it's unaffected and ARM ... well, I doubt it will be. In general, I don't think we have a big issue here by just flagging them all. I'll send an updated series with just the flag name changed as suggested by Alex and the DMA bits updated as suggested by Takashi.
