Perhaps its time, yes. Some questions:

Do these tests assume that perf was built in some particular way, i.e.
as it is packaged for RHEL?

One thing that came to mind from a report from Kim Phillips, that I
addressed (to some extent) after this sending this first patchkit to
Ingo was that perf can be built in many ways, for instance, without
'perf probe', or with 'perf probe' but without DWARF support, which will
allow some features to be tested while others should cause the test
needing not-builtin features to just return '2', that will make it be
marked as "Skip" in the output.
