And next time you want to pass something else, you'll have to touch all
those files again...

Instead, make that a notifier to which consumers register and define
a separate struct mem_err or ghes_err or whatnot and populate it with
cper_sec_mem_err data and whatever else is needed by the consumers.
Instead of passing that struct ghes * which consumers don't need to
know.

Thx.
