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"
