Sure. I'll provide it on the final patchset.

Boris suggested some alternatives for the error counter sysfs nodes, but the 
discussion ended by diverging into an implementation detail of hiding the UE
error nodes, without any consensus about the sysfs structure for it.

At the current patchset, the error counter nodes are all under
	sys/devices/system/edac/mc/mc?/

He thinks that a multi-layer struct should be created inside that directory
(it could have 2 or 3 levels of directories, depending on how the memory is
organized at the memory controller), instead of having a large number of files
there.

Anyway, before adding unnedded complexity, I'd like to hear more comments from 
the others before writing a complex patch to create such structure.

So, maybe I could just add what it was there as ABI/testing, and give more
time for kernel and userspace developers to work with it and provide us a better
feedback.

Thanks,
Mauro
