Thanks for the advice. I've looked at the commit:

   baa2cd417053 ("arm64: stacktrace: Make stack walk callback consistent 
with generic code")

The description is very clear. It describes the change in detail and
gives a reason for making that change a separate commit. The same
description applies to the current changes, so I took the commit message
directly, just made the s/arm64/ARM/ changes, and updated to v2:
