> Hi,
> below is ibmebus patch for kernel 2.6.9, ppc64/powerpc.
> I did commit it into svn contrib/ibm/gen2/backport/2.6.9.
> Since dma_addr_t is hardcoded as 32-bit number in 2.6.9 and ppc64, I need to introduce
> dma64_map/unmap_single() with result type of 64-bit, which is required by ehca.
> Thanks!

This won't work for OFED - it is built out-of-kernel,
we do not apply patches to kernel tree.

You need to add any functionality you are missing in kernel into
your module proper.
