Crashdec finding estimated hang location based on CP registers dates back prior to importing that code into mesa ~5yrs ago, fwiw.. and was improved over the years to better handle IB prefetch since then. Fwiw. It does mean for gen8 we are going to need a CPU based fallback to crashdumper to make smmu fault devcoredumps useful (since now crashdumper is needed to capture CP regs), but we need that anyways.
