-ENOPARSE. What do you mean?

Actually, with BIOS vendors wanting to do firmware-first strategy with
DRAM errors, they must have a pretty good and intimate picture of the
memory topology at hand. So it is only a logical consequence for them,
when reporting a memory error to the OS to tell us the silkscreen label
too, while at it.

And if they do that, we don't need the additional layer - just a
tracepoint from APEI and a userspace script.

It's a whole another question if they don't do that.
