iommufd/selftest: Make dirty_ops static

2024-08-19T12:26:41Z

The sparse tool complains as follows: drivers/iommu/iommufd/selftest.c:277:30: warning: symbol 'dirty_ops' was not declared. Should it be static? This symbol is not used outside of selftest.c, so marks it static.

iommu: Restore lost return in iommu_report_device_fault()

2024-08-02T13:58:05Z

When iommu_report_device_fault gets called with a partial fault it is supposed to collect the fault into the group and then return. Instead the return was accidently deleted which results in trying to process the fault and an eventual crash. Deleting the return was a typo, put it back.

iommu: arm-smmu: Fix Tegra workaround for PAGE_SIZE mappings

2024-07-25T12:08:44Z

PAGE_SIZE can be 16KB for Tegra which is not supported by MMU-500 on both Tegra194 and Tegra234. Retain only valid granularities from pgsize_bitmap which would either be 4KB or 64KB.
