[PATCH] ppc64: iommu vmerge fix
This fixes a bug in the PPC64 iommu vmerge code which results in the
potential for iommu_unmap_sg to go off unmapping more than it should.
This was found on a test system which resulted in PCI bus errors due to
PCI memory being unmapped while DMAs were still in progress.
