Good well-designed tests can help us find more bugs, especially when
the test steps differ from the Linux kernel behaviour in terms of the
timing of access to virtualized hw resources.
In this patch series, there are three small optimization (006/007/008),
one hardware surprise (001), and most of these fixes have stepped
on my little toes.
Please feel free to run tests, add more or share comments.

V2 -> V2 RESEND Changelog:
- The "pebs_capable" fix has been merged into tip/perf/tree tree;
- Move the other two AMD vPMU optimization here;
This is not a RESEND. These things very much matter because I'm sitting here
trying to figure out whether I need to review this "v2", which is really v3, or
whether I can just review the real v2.
Don't add "RESEND" when you are submitting a modified version of your
patch or patch series - "RESEND" only applies to resubmission of a
patch or patch series which have not been modified in any way from the
previous submission.
Roger that. Thanks for your detailed comments and all of that will be applied in V3.
The new AMD vPMU testcases[1] will also help guard future related changes.
