Sending this out for another round of review.

These are the main KAISER patches, on top of the preparatory series I just sent.
This includes KAISER support plus enhancements on top, all the latest code.

( All review feedback so far is incorporated - if anything is missing please
let me know. )

Thanks,

Ingo
