I don't mind if this gets merged higher up in the series, in fact, I
think it's preferred to adding the arm insn table and then removing it
in the same series.  Keeping my Author: isn't necessary either:
something like "Signed-off-by: Kim Phillips <...> [ARM bits]" will
suffice.

I'll wait for the dust to settle here before submitting an ARM return
insn fix, and aarch64 support originally authored by Chris Ryder
(basically translate table in [1] into regex format).
