I've pushed a fixed up powerpc-dma.6 tree, which will only change starting from the first commit that didn't link. The first commit that changed from the old one is this one: http://git.infradead.org/users/hch/misc.git/commitdiff/257002094bc5935dd63207a380d9698ab81f0775 which was that one that your compile failed on first. Thanks again for all your work!
