[PATCH 0/2] SWIOTLB fixes for 4.20

From: Robin Murphy

This is what I have so far, which at least resolves the most ovbious
problems. I still haven't got very far with the USB corruption issue
I see on Juno with -rc1, but I'm yet to confirm whether that's actually
attributable to the SWIOTLB changes or something else entirely.

Robin.

swiotlb: Make DIRECT_MAPPING_ERROR viable
