[PATCH v2 0/2] SWIOTLB fixes for 4.20

[Robin Murphy]

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.


Robin Murphy (2):
  dma-direct: Make DIRECT_MAPPING_ERROR viable for SWIOTLB
  swiotlb: Skip cache maintenance on map error
