the generic direct mapping bypass)

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

git checkout 21074ef03c0816ae158721a78cabe9035938dddd

I was able to compile the kernel for the AmigaOne X1000 (Nemo board with 
PA Semi PA6T-1682M SoC). It boots but the PA Semi onboard ethernet 
doesn't work.
