Its in perf/threaded at:

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git

Will continue tomorrow, testing it and checking the speedups on my
5950x, I think the things I found so far can be fixed in follow up
patches, to make progress and have this merged sooner.

I'll try and add committer notes with the test for some 'perf bench'
workload without/with parallel recording, something I missed in your
patch descriptions.
