Subject: Re: [RFC][PATCH 3/9] perf: export registerred pmus via sysfs

This really needs to loop the ARM PMU guys on this topic.  ARM PMU is
not something I know very much about, and I really don't understand
why I'm on the CC list and not the ARM PMU folk.

I may be mis-stating a problem, but I believe that we have issues with
exporting event IDs in that they're SoC implementation specific - but
as I say, the ARM PMU guys know the details not me.

I strongly suggest no further discussion without at least looping Will
Deacon in on this.
