I've queued these up now, but if you could pull the whole quilt tree and
verify I got things right, that would be great.  There was some
conflicts with a few previous patches I had already queued up that
touched some "Falkor" errata code.

Specifically 932b50c7c1c65e6f23002e075b97ee083c4a9e71 "arm64: Add
software workaround for Falkor erratum 1041" is the offending patch.  I
think I resolved the merge issues properly, but verifying this would be
wonderful.

thanks,
