Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd updates from Jason Gunthorpe: "Some polishing and small fixes for iommufd: - Remove IOMMU_CAP_INTR_REMAP, instead rely on the interrupt subsystem - Use GFP_KERNEL_ACCOUNT inside the iommu_domains - Support VFIO_NOIOMMU mode with iommufd - Various typos - A list corruption bug if HWPTs are used for attach" * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: iommufd: Do not add the same hwpt to the ioas->hwpt_list twice iommufd: Make sure to zero vfio_iommu_type1_info before copying to user vfio: Support VFIO_NOIOMMU with iommufd iommufd: Add three missing structures in ucmd_buffer selftests: iommu: Fix test_cmd_destroy_access() call in user_copy iommu: Remove IOMMU_CAP_INTR_REMAP irq/s390: Add arch_is_isolated_msi() for s390 iommu/x86: Replace IOMMU_CAP_INTR_REMAP with IRQ_DOMAIN_FLAG_ISOLATED_MSI genirq/msi: Rename IRQ_DOMAIN_MSI_REMAP to IRQ_DOMAIN_ISOLATED_MSI genirq/irqdomain: Remove unused irq_domain_check_msi_remap() code iommufd: Convert to msi_device_has_isolated_msi() vfio/type1: Convert to iommu_group_has_isolated_msi() iommu: Add iommu_group_has_isolated_msi() genirq/msi: Add msi_device_has_isolated_msi()
