I'm struggling a bit to track this. If you still think it's worth pursuing,
please could you post a series with a cover-letter describing what this is
for, a link to the userspace changes and then patches for all the PMU
drivers that need updating? There was an RFC from you for the SMMUv3 PMU as
well, and also some other "arm64" changes.

Cheers,

Will
