Done:

https://git.kernel.org/cgit/linux/kernel/git/acme/linux.git/commit/?h=perf/core&id=8affc2b8c27bfc2d6e70827b746f490b62c44eaa

Consider now pulling the perf-core-for-mingo tag there, I updated it
after updating the changelog for this specific commit, all the
rest is the same as in the previous pull req.

Thanks,
