                For now, we'll add some padding to scsipi_xfer so that
                the corrupted memory is not otherwise used.

+               sys/arch/powerpc/oea/pmap.c cannot be compiled with
+               -Wcast-qual because "volatile struct pteg *pmap_pteg_table"
+               is being passed to memset(), and the only obvious
+               alternative to adding -Wno-cast-qual I could see would
+               be to open-code memset(), which I think would be worse
+               than this fix.
