Basically it all went very well. However for my test
configuration the 2 MB chosen for the DMA page pool
size wasn't quite enough. So I think we need the kernel
parameters as suggested by Dan Hollis.
Also the implementation seems to give up when the
2 MB is exhausted without checking the main pool.
[Hopefully I'm wrong here].
This patch is obviously not architecturely independent
so we need to think how to handle this. For example,
the second page pool (for DMA) is only generated on
architectures that need it.
