Here's a quick v2 addressing Christoph's nits and collecting the tags given so far. I've reproduced my USB problem with a commit prior to the dma-mapping pull, so it looks like the cache maintenance changes are off the hook for that one (and I'll have to venture into USB/UAS territory).
No objection from me if Konrad wants to pick this up instead depending on timing. Robin.
