Subject: [PATCH v2 0/4] Add VG register attr test with kernel version and feature detection

I didn't get any feedback on the RFC version of this that I posted a
while back [1]. I'd still like to add the test, especially now that
6.1 has been released with this new feature, so I've rebased it onto
perf/core and double checked that it's still working.

Applies to perf/core (0c3852adae83)

Thanks
James
