[ 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.
