From: Heiko Carstens <hca@xxxxxxxxxxxxx> [ Upstream commit f09354ffd84eef3c88efa8ba6df05efe50cfd16a ] There are many different types of translation exceptions but only a translation-specification exception leads to a kernel panic since it indicates corrupted page tables, which must never happen. Improve the panic message so it is a bit more obvious what this is about.
