You actually don't need to modify (m)any source files.

Here is an alternative approach.  These patches depend on Olaf's
boot code cleanup for ppc64 (or similar).  Do the following:

cd linux/include
mkdir asm-powerpc
cd asm-ppc
for i in *
do
	[ -e ../asm-ppc64/$i ] || mv $i ../asm-powerpc/$i
done
cd ../asm-ppc64
for i in *
do
	[ -e ../asm-ppc/$i ] || mv $i ../asm-powerpc/$i
done
for i in *
do
	[ -f ../asm-ppc64/$i ] && cmp -s $i ../asm-ppc64/$i &&
		mv $i ../asm-powerpc/$i && rm ../asm-ppc64/$i
done

Then apply the patch below and the patch in the following email.

I have built this kernel for ppc (defconfig), ppc64 (iSeries, pSeries and
pmac).
