... and it all looks pretty damn good to me. I gave you a few in-line
comments but, rather than repeat myself for each patch, my main two gripes
were:

  - The use of BUG_ON all over the place

  - Explicit limit checks which could be done with masks

If you address those, this stuff looks pretty much ready to go from my
perspective. Do you have a branch somewhere I can play with please?

Cheers,

Will
