Hi,

I updated the patches to 2.4.6-pre5, and removed the zone-dma32
addition. This means that machines with > 4GB of RAM will need to go all
the way to low mem for bounces. I did this for several reasons:

- Linus didn't like the extra zone, so I'm probably redoing it the way
  he suggested.
- The current version had a bug that prevented 64GB highmem working.

The core has received no other updates that removal of GFP_DMA32 parts
and gfp_mask for bouncing.

I can't put the patch on kernel.org atm, so I've just attached it here.
It's not that big anyway. As soon as I can log back in, I'll post it
there too.
