This seems to be happening because we now allow sg merging through the BIOVEC_MERGEABLE macro. On ppc64 (and sparc64) we can coalesce two sg entries if the first one ends on a page boundary and the next one starts on a page boundary because we have an IO MMU. (I know that you know this, Im just explaining it for those who dont :)
In that case you perhaps should be defining DMA_CHUNK_SIZE in asm/dma.h :-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
