Merge branch 'iommufd/for-rc' into for-next

The following selftest patch requires both the bug fixes and the
improvements of the selftest framework.

* iommufd/for-rc:
  iommufd: Do not corrupt the pfn list when doing batch carry
  iommufd: Fix unpinning of pages when an access is present
  iommufd: Check for uptr overflow
  Linux 6.3-rc5
