Hi all, Round 3, and the patch count has crept up yet again. But the overall diffstat is even more negative, so that's good, right? :) Once again, to driver/platform maintainers CC'd on cookie cleanup patches this is just a heads-up and the rest of the changes should not affect your platforms. I hope I've now fixed the silly bug which broke bisection between patches #1 and #12 on 32-bit Arm. The new patches are in the middle, reworking how the SMMU drivers and io-pgtable implement non-strict mode such that the later changes fall into place even more easily. Turns out I didn't need the major refactoring of io-pgtable that I had in mind, and I'm almost kicking myself that as soon as I put the option of *not* using the existing quirk on the table, an even cleaner and more logical solution was staring right out at me. Due to that signifcant change and the consequent redesign of the final patch to make dynamic switching look viable in the face of concurrency, I have not applied the tested-by tags from v2. They were very much appreciated though, thanks! Proper changelogs on the individual patches this time since otherwise I'd have lost track... Cheers, Robin.
