Hi all,

Here's a re-worked set for c/r of seccomp filters which keeps around the
original bpf program passed to the kernel instead of trying to dump the
ebpf version. There are various comments/questions in the individual patch
notes.

I'm not sure this needs to go via net-next any more, as the impact in net/
is fairly minimal, and it seems more seccomp heavy. As such, this set is
based on seccomp/tip.

Thoughts welcome,

Tycho

P.S. Man page patches to come once we agree on the API :)
