Hi all,
is there a *direct* future-proof replacement for bus_to_virt()?
It appears there are already architectures which do not define a
bus_to_virt() funtion or macro. If there isn't a direct replacement, is
there at least a way to detect at compile time whether bus_to_virt() exists?
I'd go one step further: given a world with iommu's, and multiple pci
domains etc, how can you know there even IS such a translation possible
(without first having set it up from the other direction)?
