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
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 test your DMA changes in the next merge window again. :-)
