Bah, look how time flies... :-\

Good catch - I had completely forgotten about this gunk.

Yeah, you set it to default n in Kconfig and add a warning when someone reads
the old sysfs nodes. Something along the lines that this interface has been
deprecated for a decade now and that people should switch to the new dimm
interface and that it will be removed in, say, 2-3 kernel releases or so.

I'd say.

Thx.
