arm64: errata: Enable TRBE workaround for write to out-of-range address (2021-10-25 12:06:02 -0600)
----------------------------------------------------------------
Coresight changes for v5.16
- A new option to make coresight cpu-debug capabilities available as early
as possible in the kernel boot process.
- Make trace sessions more enduring by coping with scenarios where events
are scheduled on CPUs that can't reach the selected sink.
- A set of improvement to make the TMC-ETR driver more efficient.
- Enhancements to the TRBE driver to correct several errata.
- An enhancement to make the AXI burts size configurable for TMC devices
that can't work with the default value.
- A fix in the CTI module to use the correct device when calling
pm_runtime_put()
- The addition of the Kryo-5xx device to the list of support ETMs.

Better but I get the following errors when my scripts try to merge them.
Note, the linux-next scripts will give you the same complaint, so this
isn't a new thing:

Errors in tree with Signed-off-by, please fix!
Is there some reason you are committing changes to your tree and not signing
off on them? That's not really a good idea :(

Is this tree/branch in linux-next now? If so, you should have gotten an
email.
My scripts were sent to the workflow mailing list a year or so ago, I
can dig them up if needed.

Can you point me to the linux-next script you are referring to above?
Usually when that happens I get an email but this time I didn't get
anything.

Not sure why sarcasm is required here - simply pointing out the
problem would have been sufficient.
These patches were committed by Suzuki who co-maintains the subsystem
with me. The committer information likely got transferred when I
cherry-picked the patches when putting the pull request together.

Thanks - I'll look it up.
