This updated tree now includes a fix for virtio-net regression that was
present in 5.14:

virtio-net: fix for skb_over_panic inside big mode
commit 126285651b7f ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net")
accidentally reverted the effect of
commit 1a8024239da ("virtio-net: fix for skb_over_panic inside big mode")
on drivers/net/virtio_net.c
As a result, users of crosvm (which is using large packet mode)
are experiencing crashes with 5.14-rc1 and above that do not
occur with 5.13.

Bumping the OVMF binary version along with UEFI documentation to
reflect the latest set of patches on top of tianocore/edk2 'master'
branch, which can be found on the Cloud Hypervisor fork on 'ch' branch.

This script checks if an image is compatible with Cloud Hypervisor.
At first, it detects the image type(raw or qcow2),
partition type whether it is DOS or GPT.
Then it mounts the image and checks if VIRTIO Configs
are enabled in the kernel config. In the end, it provides
a message about the compatibility of the image.

In integration test, we fetch latest EDK2 code on its master branch and
build. While the update on EDK2 master is frequent. And the building is
time consuming. It takes a lot of time in CI and local test. Floating on
top of a busy master branch also bring potential risk in tracking and
debugging.
Now that Cloud Hypervisor support in EDK2 has been steady, we can pin
the EDK2 software versions to avoid unnecessary updating and building.
We can update the versions manually every after several months.
The commit also optimizes the build process by applying multi-threaded
compiling.

On AArch64, ACPI must work with UEFI (EDK2). This way, the kernel is
always loaded from the disk image. We can not specify a direct custom
kernel while using ACPI.
To use a custom kernel, we have to replace the kernel file in the disk
image by:
- Making a copy of the Focal `raw` image
- Mounting the rootfs with `libguestfs-tools`
- Replacing the compressed kernel file

Moving to the latest kernel 5.14 simplifies greatly the list of patches
that we need to carry. Since virtio-iommu has been merged as part of the
5.14 release, the only remaining patches are virtio-watchdog and the EFI
reboot.

The edk2 upstream has already suppoorted AArch64 Cloud Hypervisor,
and hence we can use upstream edk2 in CI and doc.

AArch64 tests were divided into 2 steps:
- Build and test with 'acpi' feature
- Build and test without 'acpi'
This can be optimized. We need only to build and test once with default
features ('acpi' is enabled).
On AArch64, ACPI only works with UEFI. If UEFI is not available, guest
kernel fall back to use FDT. Most AArch64 test cases boot from direct
kernel, the guest will keep using FDT even if ACPI is enabled. So
nothing is broken.

Since using the VIRTIO configuration to expose the virtual IOMMU
topology has been deprecated, the virtio-iommu implementation must be
updated.
In order to follow the latest patchset that is about to be merged in the
upstream Linux kernel, it must rely on ACPI, and in particular the newly
introduced VIOT table to expose the information about the list of PCI
devices attached to the virtual IOMMU.

(cherry picked from commit 2aec0a92a5)
In order to avoid regression regarding OVS-DPDK support, a new
integration test is added. This test consists of running two VMs, both
attached to a distinct OVS port, where both ports are connected to an
OVS bridge. Once the VM are running, the test validates the connection
between the two VMs works correctly.

Relying on dnsmasq running on the host, the Windows guest are now
getting allocated with the expected IP addresses. This allows for
multiple VMs, therefore multiple tests to run in parallel.
The end goal is to reduce the time spent running Windows integration
tests.

Relying on guest Ubuntu image 21.04, including a 5.11 kernel, this patch
adds some additional tests to the VFIO baremetal integration tests. It
adds a test for ACPI memory hotplug, another one for virtio-mem memory
hotplug, and finally a test for hotplugging the NVIDIA card.
The existing test already taking care of the reboot has been renamed.
The script running "cargo test" has been modified to run only one thread
at a time, so that each test run sequentially. This is mandatory since
the card can't be shared across multiple VMs.
