I did not do that, intentionally.  The reason is that the
existing code only supports IPA v3.5.1 and IPAv4.2.  And
these bugs seem to cause no problems there.

There are some patches coming very soon that will add
more formal support for IPA v4.5 (where I know you
found these issues).  Those will not be back-ported.

So these fixes don't appear to be necessary for existing
supported platforms.

If you still believe I should have these back-ported,
I have no objection to re-posting for that.  But I
wanted to explain my reasoning before doing it.

Thanks.
