Hi Dave,

V1 patches:
http://thread.gmane.org/gmane.linux.kernel/1605783
V2 patches:
http://thread.gmane.org/gmane.linux.kernel/1642325
V3 patches:
http://thread.gmane.org/gmane.linux.kernel/1656538

V4 summary:
- addressed Daniel comments
- RFC for seccomp with extended BPF
- added extended BPF design doc

V5 summary:
- fixed commit one-liner, removed empty line
- added Hagen's ack

V6 summary:
- unrolled loop in populate_seccomp_data() to help gcc on arm
- removed empty line at the end of the file
- removed redundant (u32) cast in JSET
- fixed BPF_RVAL instead of BPF_SRC for BPF_RET in sk_convert_filter()
- updated commit log
- added Daniel's Reviewed-by
- added Kees's Reviewed-by

V7 summary:
1/3:
- addressed Dave's feedback regarding typecasting:
  added 'jited' flag to sk_filter and union for bpf_func/bpf_func_ext
- added a comment to sk_run_filter_ext() about ctx<->skb relation
- removed CPU specific code from sk_run_filter() and sk_run_filter_ext()
  because of that revised arm32 cache-hit bpf micro-bench numbers slightly
  slower, but seccomp and cache-miss arm32 numbers stayed the same
2/3 and 3/3: no changes

x86_64, i386 and arm32 look clean.

Thanks!
