Unfortunately, that is correct. :-\

I'd be interested as to why. Because decoding addresses is amd64_edac
*core* functionality. We can stick it in drivers/edac/mce_amd.c but I'd
like to hear what those valid reasons are, not to use the driver which
is supposed to do that anyway.

Thanks for explaining - it is all clear now.
