Ok, after setting up cross compile environments for sparc64 and
powerpc64 I wrote a patch which adds the io_page_size argument to the
iommu_num pages function and moves the function back to
lib/iommu-helper.c. The patch touches all 3 architectures and can not be
split in a bisectable way.

Who is the best person to send this patch to?
