Hi Linus,

Nothing big this time, I was hoping viommu would make it, but not yet.

There is a small merge conflict "take mine" to resolve, the mm tree
added a debugfs.h include to a file that mine already has.

The tag for-linus-iommufd-merged with my merge resolution to your tree
is also available to pull.

Thanks,
Jason

  iommu: Set iommu_attach_handle->domain in core (2024-09-11 20:14:07 -0300)

----------------------------------------------------------------
iommufd 6.12 merge window pull

Collection of small cleanup and one fix:

- Sort headers and struct forward declarations

- Fix random selftest failures in some cases due to dirty tracking tests

- Have the reserved IOVA regions mechanism work when a HWPT is used as a
  nesting parent. This updates the nesting parent's IOAS with the reserved
  regions of the device and will also install the ITS doorbell page on
  ARM.

- Add missed validation of parent domain ops against the current iommu

- Fix a syzkaller bug related to integer overflow during ALIGN()

- Tidy two iommu_domain attach paths

----------------------------------------------------------------
