For the first 3 patches in my series I am fine with them being pulled into the swiotlb tree.  So if you want to pull Christoph's two patches, and then drop my duplicate patch and instead pull the next 2 I could submit a v3 of my series without the swiotlb patches in it.

At this point I have redone my series so that I technically don't have anything with a hard dependency on the DMA_ATTR_SKIP_CPU_SYNC actually doing anything yet.  My plan is to get this all into Linus's tree first via whatever tree I can get these patches pulled into and once I have all that I will start updating drivers in net-next.

Thanks.
