Hmm, yes that's true. I guess we can make it default to opt-in for
pci_iomap.

It only really matters for device less ioremaps.

OK. And same thing for other things with device, such as
devm_platform_ioremap_resource.
If we agree on all that, this will basically remove virtio
changes from the picture ;)

Hi we revisited this now. One problem with removing the ioremap opt-in 
is that it's still possible for drivers to get at devices without going 
through probe. For example they can walk the PCI device list. Some 
drivers do that for various reasons. So if we remove the opt-in we would 
need to audit and possibly fix all that, which would be potentially a 
lot of churn. That's why I think it's better to keep the opt-in.
