FWIW, I want to add a Documentation/arm64/unwinding.{whatever} to give links to
the relevant documentation (e.g. the AAPCS64 docs) and to explain the
arm64-specific unwinding concerns, but I haven't had the chance to write that
yet.

Either way I'd like to remove this comment since it's both misplaced and
misleading, so thanks for the Reviewed-by tag!

Mark.
