Yeah, I made some progress and have a whole bunch of patches to post
which I had hoped to do last week.  Unfortunately the move to the UK
has meant that the last 7 days have been non-stop cleaning, packing
and throwing out stuff.  I've not been able to do a final cleanup.
The house gets cleaned on Tuesday so it can go on the market on
Wednesday which means all the house stuff must be done by Monday
evening.  Hopefully I'll get some time on Tuesday to do some hacking.

If you want to look at them I've pushed them out to the irqdomain/test
branch on git.secretlab.ca.
