powerpc: Reduce scariness of interrupt frames in stack traces
Some people see things like "Exception: 501" in stack traces in dmesg and assume that means that something has gone badly wrong, when in fact "Exception: 501" just means a device interrupt was taken. This changes "Exception" to "interrupt" to make it clearer that we are just recording the fact of a change in control flow rather than some error condition.
