Thanks for the updated patches and sorry for the delay in reviewing them.

I responded with some minor nits on patches 1/4 and 2/4.
The other patches 3/4 and 4/4 look good to me.

Modulo any feedback from others I'd be happy to move forwards
with applying this series once my nits have been addressed
(via email or fresh patches).

Thanks again,
Simon
