Can you strip out the arch bits and just send me the block bits? The arch bits should go in via the arch maintainers. The iommu code may still do virtual merging, it would be silly not to do that if possible. Now that later kernels expose the necessary parameters at that level as well, it's perfectly feasible. -- Jens Axboe
