Joyce is no longer with Arm, and we have not been able to figure out
this patch. I think the first patch of this series makes sense.
This second patch to us looks like a nice to have, rather than something
that fixes an issue. Therefore, we would like to pull this patch out of the
series and leave first patch intact. 
Any concerns/comments on that?
