I think I have explained it clearly enough in this email:
Link: https://lore.kernel.org/20251104133254.145660-1-xieyuanbin1@xxxxxxxxxx

In simple terms, it refers to some old existing equipment and some
embedded devices. More specifically, it includes some routers, switches,
and similar devices. From what I know, there is no VM environment that
using it.
If you are asking about a specific CPU chip model, I'm sorry, but I may
not be able to provide that information for you.

Btw, why do you only ask about which x86_32 devices use memory-failure,
but not which x86_32 devices use sparsemem? This patch just allows both
to coexist, and perhaps both are important?

Thanks!
