Pull iommufd updates from Jason Gunthorpe: "No major functionality this cycle: - iommufd part of the domain_alloc_paging_flags() conversion - Move IOMMU_HWPT_FAULT_ID_VALID processing out of drivers - Increase a timeout waiting for other threads to drop transient refcounts that syzkaller was hitting - Fix a UBSAN hit in iova_bitmap due to shift out of bounds - Add missing cleanup of fault events during FD shutdown, fixing a memory leak - Improve the fault delivery flow to have a smaller locking critical region that does not include copy_to_user() - Fix 32 bit ABI breakage due to missed implicit padding, and fix the stack memory leakage" * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: iommufd: Fix struct iommu_hwpt_pgfault init and padding iommufd/fault: Use a separate spinlock to protect fault->deliver list iommufd/fault: Destroy response and mutex in iommufd_fault_destroy() iommufd: Keep OBJ/IOCTL lists in an alphabetical order iommufd/iova_bitmap: Fix shift-out-of-bounds in iova_bitmap_offset_to_index() iommu: iommufd: fix WARNING in iommufd_device_unbind iommufd: Deal with IOMMU_HWPT_FAULT_ID_VALID in iommufd core iommufd/selftest: Remove domain_alloc_paging()
