Yep, as I said to Stephen earlier in this thread, I think I mistakenly
searched for 64_BIT; unfortunately I can't tell since all history has is:

   16  make  O=../ppc-build/ pasemi_defconfig
   17  vi ../ppc-build/.config

Anyway, that mis-documentation in the commit log aside, it seems like
the driver has been pulled from the linux-next content for today;
presumably to be reworked and resubmitted with better arch coverage
to address all the issues raised here.  That is probably the right
approach - we don't need to pollute git history with all that..

Thanks,
Paul.
