And that was the motivation behind my splitting it in this patch.

My apologies, sometimes my thought is too far ahead of my typing
fingers. For the purpose of handling _one_ error, you need the CPER
entry for that one error -- narrow context. You don't need the entire
GHES structure -- wide context. Individual handlers should not be able
to access the entire ghes.

When the handlers are restricted to a common signature --which doesn't
include ghes--, it's obvious when functions try to bite more than they
can chew.
