I assume that this has something to do with:
commit 650320181a08b64d4421c65c639cf47ad8cc2cd6

ARM: change ARM_DMA_ZONE_SIZE into a variable
commit 7553ee777b513c3bc8f45bb9fc75fb1bbc584ba1
Author: Nicolas Pitre <nicolas.pi...@linaro.org>
Date: Tue Jul 5 22:28:09 2011 -0400
ARM: mach-ixp4xx: move from ARM_DMA_ZONE_SIZE to mdesc->dma_zone_size
It's clear that the DMA zone size is supposed to be 64 MB on this
machine and I don't see why the DMA mask hasn't propagated correctly.
Any idea, Nicholas?
Ben.
