These all look good to me. I had some minor comment about one patch but 
not really a big deal and there were more cleanups on top of it, so I 
don't mind if it's merged as is.

Actually I think we have a bit of stack reading fixes for 64s radix now
(not a bug fix as such, but we don't need the hash fault logic in radix),
so if I get around to that I can propose the changes in that series.

Thanks,
Nick
