A couple of changes related to edge cases since commit 8d3031d39fe8 ("perf cs-etm: Track exception level").
I think the second one is low risk seeing as any path requiring a thread leading up to adding to the histogram would already have been crashing. Maybe the thread check could also be added to hist_entry_iter__add() although other users of it don't seem to have the same issue, and there is another use of al.thread above in builtin-report.c so it's probably ok where I've added it.
Applies to perf-tools-next/perf-tools-next (929ff679b69)
