Hi,

So my series is now on remotes/origin/tmp.perf/core in Arnaldo's acme 
git, so you could resend against that.

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

Or again, put my series on perf/core and send against that.

As for patch 3/4, firstly I'd say that it is not a 'fix'. As well, 
please ensure it causes no regression on x86 or arm64. So like "perf 
list" output is same as before (with just that change), and also test 
some same perf events and metrics (x86 only) to ensure that they are ok. 
Please also ensure no regression on "perf test".

BTW, please config your mail client for no text encoding.

Thanks,
John
