Instead of extending this bad scaling dmesg error-reporting mechanism, I
would very much like to see an integration of IOMMU error handling into
the EDAC framework.
An exception is of course still the flags decoding in this patch-set.
This alone would be pretty compelling as long as there is no integration
into EDAC.
