David Matlack d8470a775c vfio: selftests: Support multiple devices in the same container/iommufd
Support tests that want to add multiple devices to the same
container/iommufd by decoupling struct vfio_pci_device from
struct iommu.

Multi-devices tests can now put multiple devices in the same
container/iommufd like so:

  iommu = iommu_init(iommu_mode);

  device1 = vfio_pci_device_init(bdf1, iommu);
  device2 = vfio_pci_device_init(bdf2, iommu);
  device3 = vfio_pci_device_init(bdf3, iommu);

  ...

  vfio_pci_device_cleanup(device3);
  vfio_pci_device_cleanup(device2);
  vfio_pci_device_cleanup(device1);

  iommu_cleanup(iommu);

To account for the new separation of vfio_pci_device and iommu, update
existing tests to initialize and cleanup a struct iommu.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
