See the cover letter for changes. They address the sashiko reviews,
you may not see these reviews as they are only sent to me and
linux-perf-users, which is somewhat customary in the sashiko setup.

I don't see any relevance in rc7, I'm just mailing out a new driver
now that I have the opportunity to look at it. Whether and when it
gets pulled upstream is up to a maintainer. Another useful series to
pull would be (imo):
https://lore.kernel.org/linux-perf-users/20260101-apple-cpmu-v10-0-48812c529ffc@gmail.com/

The changes are sent in reply to each other because the entire series
is visible in one mailbox (b4 mbox), which I find easier to work with
and provides me better context. Others use semcode to do something
similar, but I've not explored that.

Let me know if I should drop you from the cc, I placed you there as
Mark and you were the only suggested reviewers from
scripts/get_maintainer.pl but I don't want to spam uninterested
people.

Thanks,
Ian
