I'm just wondering, next to the feedback that has already been provided, would opening this up for ppc32 make it significantly more difficult in future to migrate from classic BPF JIT to eBPF JIT eventually (which is what we want long-term)? Being curious, is there any ongoing effort from ppc people?
