Based on patch by David Gibson <dwg@au1.ibm.com> xmon has a longstanding bug on systems which are SMP-capable but lack the MSR[RI] bit. In these cases, xmon invoked by IPI on secondary CPUs will not properly keep quiet, but will print stuff, thereby garbling the primary xmon's output. This patch fixes it, by ignoring the RI bit if the processor does not support it. There's already a version of this for 4xx upstream, which we'll need to extend to other RI-lacking CPUs at some point. For now this adds Book3e processors to the mix.
