We retain the classic BPF JIT for ppc32 and move ppc64 BE/LE to use the new JIT. Classic BPF filters will be converted to extended BPF (see convert_filter()) and JIT'ed with the new compiler. Most of the existing macros are retained and fixed/enhanced where appropriate. Patches 1-4 are geared towards this. Patch 5 breaks out the classic BPF JIT specifics into a separate bpf_jit32.h header file, while retaining all the generic instruction macros in bpf_jit.h. Most of these macros can potentially be generalized and moved to more common code (tagged with a TODO in patch 6). Patch 6 implements eBPF JIT for ppc64. This is still *early* *RFC* and there are still a few instruction classes to be JIT'ed. I am posting this in advance so as to get early feedback. Kindly review the same and if possible, try it out and let me know how it goes! - Naveen Naveen N.
