Robin Murphy 7618e47909 iommu/io-pgtable-arm: Improve attribute handling ... By VMSA rules, using Normal Non-Cacheable type with a shareability attribute of anything other than Outer Shareable is liable to lead into unpredictable territory: | Overlaying the shareability attribute (B3-1377, ARM DDI 0406C.c) | | A memory region with a resultant memory type attribute of Normal, and | a resultant cacheability attribute of Inner Non-cacheable, Outer | Non-cacheable, must have a resultant shareability attribute of Outer | Shareable, otherwise shareability is UNPREDICTABLE Although the SMMU architectures seem to give some slightly stronger guarantees of Non-Cacheable output types becoming implicitly Outer Shareable in most cases, we may as well be explicit and not take any chances. It's also weird that LPAE attribute handling is currently split between prot_to_pte() and init_pte() given that it can all be statically determined up-front. Thus, collect *all* the LPAE attributes into prot_to_pte() in order to logically pick the shareability based on the incoming IOMMU API prot value, and tweak the short-descriptor code to stop setting TTBR0.NOS for Non-Cacheable walks.
