Ok, then I'll send it out as part of the larger RFC set.

The most basic questions, that I hope can be answered with Yes/No =) are:

- should a new zone be added after DMA32?

- should I try hard to keep the mask fitting a 32bit word - at least for
hose who do not use the new zone - or is it ok to just stretch it to 64
bits?



If you could answer these, then I'll have a better idea of what I need
to do to.
