Then uplayer could know when/why/what happened during hitting a hardware memory failure. Suggested by Peter Maydell, rename events name&description to make them architecture-neutral; and suggested by Paolo, add more info to distinguish a mce is AR/AO, previous mce is still processing in guest or not.
