yep, its in my perf/core branch:

https://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git/commit/?h=perf/core&id=cf7905165fee15fe26ac4a91ee0a35b966249430

I'll process some more patches from Adrian and Andi today, both making
use of Intel Xed, that seems to be installed ok now in my test machines,
and then send a pull req to Ingo,

Thanks,
