I already sent:

  https://lore.kernel.org/r/20260617130038.34534-1-broonie@xxxxxxxxxx

which I have been using as a fixup since I originally reported the issue
since Linus' tree is broken, Arnaldo said he'd applied it to the
perf-tools-next branch but it has not yet appeared in Linus' tree (and
it looks like he forgot to push it so his copy isn't getting picked up
in the merge either, the last update was on the 15th).
