Do you know where i can ping the powerpc guys a little bit harder?maybe using CC linux-arch@vger.kernel.org One way to handle that would be to split this patch in 3 parts, so that I can Ack the non ppc part. [1] introduce bpf_internal_load_pointer_neg_helper() [BTW no need to EXPORT_SYMBOL it, since jit is not a module ] [2] x86_bpf_iit: handle negative offsets in loads [3] ppc_bpf_jit: handle negative offsets in loads
Yeah, that'd be great, then I can stew on it without holding you up further. Cheers, Matt
