[PATCH v2 0/3] Add iommufd ioctls to support TSM operations

[Aneesh Kumar K.V (Arm)]

This patch series adds iommufd ioctl support for TSM-related operations.
These ioctls allow VMMs to perform TSM management tasks such as bind/unbind
operations and handling guest requests.

This series is posted separately in v2. The v1 posting is available at:
https://lore.kernel.org/all/20250728135216.48084-8-aneesh.kumar@xxxxxxxxxx

Changes from v1:
* Rebased onto the latest kernel
* Addressed review feedback
* Dropped the TSM map ioctl; the KVM prefault patch will be used instead to
  ensure private memory is preallocated

Aneesh Kumar K.V (Arm) (3):
  iommufd/viommu: Allow associating a KVM VM fd with a vIOMMU
  iommufd/tsm: add vdevice TSM bind/unbind ioctl
  iommufd/vdevice: add TSM guest request ioctl
