Thanks for the report, fixed, the issue was that Ian's S-o-B was after a
--- line and thus git-am chopped it up :-\
===============================================================================
When the cycles event isn't available evsel will fallback to the
cpu-clock software event. task-clock is similar to cpu-clock but only
runs when the process is running. Falling back to cpu-clock when not
system wide leads to confusion, by falling back to task-clock it is
hoped the confusion is less.
Pass the target to determine if task-clock is more appropriate. Update
a nearby comment and debug string for the change.

v2. Use target__has_cpu as suggested by Namhyung.

I'll check my pre-commit hooks to see why this didn't get flagged...
