Okay, my believe until yesterday was that EDAC provides a consistent way
to report hardware errors to userspace. That seems to be wrong. This in
mind I think having a trace-point for that makes sense.

But this trace-point must not be specific to a single IOMMU driver, I
want it generic enough so that it can be used by all common IOMMU
drivers to report hardware misbehaviors to userspace.

Thanks,
