Yup rebase glitch. .../... > I tested it on the 8xx with the below changes in addition. No issue seen > so far. Thanks ! I'll merge that in. The main obscure area is that business with the irqsoff tracer and thus the need to create stack frames around calls to trace_hardirqs_* ... we do it in some places and not others, but I've not managed to make it crash either. I need to get to the bottom of that, and possibly provide proper macro helpers like ppc64 has to do it. Cheers, Ben.
