Hi Stefan, The references dynamic vcpu tracing support was removed when the original TCG trace points where removed. However there was still a legacy of dynamic trace state to track this in cpu.h and extra hash variables to track TBs. While the removed vcpu tracepoints are not in generated code (or helpers) they still bring in a bunch of machinery to manage the state so I've pulled them out. We keep and rename one (cpu_reset) to a static trace points which dump vcpu->index as it is useful to f4bug.
v3 fixes some minor comments and instead of simplifying to qemu_xxhash6 we extend to qemu_xxhash8 so we can include cs_base. I've added some initial benchmarks to the comments but you might want to drop the last patch and leave it up to Richard to queue via his tree once you've merged. Please queue into your tree.
