Why would we want to lie about deferred errors being uncorrectable?

And I believe deferred errors can be handled differently like freeze the
process using the page instead of killing it. And so on...

Why aren't you simply adding the documentation about
HW_EVENT_ERR_DEFERRED and be done with it? The downstream path like
tracepoint and all can handle all that just fine.

No can do. It is a public branch and there's no touching it.
