Merge tag 'iommu-fixes-v6.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux
Pull iommu fixes from Joerg Roedel: - Fix a device-stall problem in bad io-page-fault setups (faults received from devices with no supporting domain attached). - Context flush fix for Intel VT-d. - Do not allow non-read+non-write mapping through iommufd as most implementations can not handle that. - Fix a possible infinite-loop issue in map_pages() path. - Add Jean-Philippe as reviewer for SMMUv3 SVA support * tag 'iommu-fixes-v6.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux: MAINTAINERS: Add Jean-Philippe as SMMUv3 SVA reviewer iommu: Do not return 0 from map_pages if it doesn't do anything iommufd: Do not allow creating areas without READ or WRITE iommu/vt-d: Fix incorrect domain ID in context flush helper iommu: Handle iommu faults for a bad iopf setup
