Subject: Re: use generic DMA mapping code in powerpc V4

Next step: 891dcc1072f1fa27a83da920d88daff6ca08fc02 (powerpc/dma: remove 
dma_nommu_dma_supported)

git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.6 a

git checkout 891dcc1072f1fa27a83da920d88daff6ca08fc02

Output:

Note: checking out '891dcc1072f1fa27a83da920d88daff6ca08fc02'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b <new-branch-name>

HEAD is now at 891dcc1... powerpc/dma: remove dma_nommu_dma_supported

Link to the Git: 
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/powerpc-dma.6

Results: PASEMI onboard ethernet works and the X5000 (P5020 board) 
boots. I also successfully tested sound, hardware 3D acceleration, 
Bluetooth, network, booting with a label etc. The uImages work also in a 
virtual e5500 quad-core QEMU machine.
