I've been going back and forth on this, and I think what I've settled
on is I'd like to avoid new CONFIG dependencies just for this feature.
Instead, how about we just fill in SECCOMP_NATIVE and SECCOMP_COMPAT
for all the HAVE_ARCH_SECCOMP_FILTER architectures, and then the
cache reporting can be cleanly tied to CONFIG_SECCOMP_FILTER? It
should be relatively simple to extract those details and make
SECCOMP_ARCH_{NATIVE,COMPAT}_NAME part of the per-arch enabling patches?

Sorry, the 5.10 merge window is already closed for stuff that hasn't
already been in -next. Most subsystem maintainers (myself included)
don't take new features into their trees between roughly N-rc6 and
(N+1)-rc1. My plan is to put this in my -next tree after -rc1 is released
(expected to be Oct 25th).

I'd still like to get more specific workload performance numbers too.
The microbenchmark is nice, but getting things like build times under
docker's default seccomp filter, etc would be lovely. I've almost gotten
there, but my benchmarks are still really noisy and CPU isolation
continues to frustrate me. :)
