[POWERPC] pasemi: Fix iommu + 64K PAGE_SIZE bug
The powerpc iommu code was refactored by Linas back in the 2.6.20 time frame to map 4K pages from the generic code, but I had forgotten to go back and fix my platform driver before submitting it. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
