Subject: fix SG list handling in the sparc32 iommu driver

Hi Dave,

this series fixes some long standing bugs in the sparc32 iommu driver,
mostly the lack of handling of large sglist offsets in the map_sg
method, but also a few other smaller bits.  These now show up all the
time do some block layer changes in linux-next.
