Good catch.

I think I wanna do something like this:

	if (memory_error(m) && !(m->status & MCI_STATUS_UC) ...

as we want to make sure we're looking at a memory error first and then
decide on severity.

Alternatively I could stick that logic in another helper called
correctable_memory_error() or so but I don't have a strong preference.

Thanks.
