I tested the whole series today. The kernels boot and the P.A. Semi
Ethernet works! :-) Thanks a lot!

I also tested it in a virtual e5500 QEMU machine today. 
Unfortunately the
kernel crashes.

This looks like a patch I fixed in mainline a while ago, but which
the powerpc tree didn't have yet.

I've cherry picked this commit
("swiotlb: clear io_tlb_start and io_tlb_end in swiotlb_exit")

and added it to the powerpc-dma.6 tree, please retry with that one.

Hello Christoph,

Have you added it to the powerpc-dma.6 tree yet? The last commit was 
4 days
ago.

I added it, but forgot to push it out.  It is there now, sorry:

Hi Christoph

Many thanks! Your Git kernel works in a virtual e5500 machine now! :-)

I think we have reached the end of testing! All things are working 
with your DMA updates.

I am looking forward to testing your DMA changes in the next merge 
window again. :-)

Cheers
Christian
