Well if you want to keep them we should not apply patch #3 then since
we're the only users of it :-)
I'm ok with dropping #3/#4 if you want (also less work for Alex since we
won't have to prune that history out of the branch we submit upstream).
umr has already been ported over to the new iova file though so it won't
be using the trace.
Cheers,
Tom
