653087d7a3 vmm: Reduce MMIO address space by 4KiB
In order to workaround a Linux bug that happens when we place devices at
the end of the physical address space on recent hardware (52 bits limit)
we reduce the MMIO address space by one 4k page. This way, nothing gets
allocated in the last 4k of the address space, which is negligible given
the amount of space in the address space.

5f9e079a03 device: Add AArch64 RTC PL031 implementation
This commit adds the implementation for the AArch64 PL031
Real Time Clock (RTC) that provides a long time base counter. This
is achieved by generating an interrupt signal after counting a
programmed number of cycles of a real-time clock input. The AArch64
guest VM of the cloud-hypervisor will use this RTC to sync the time
in itself.

This removes the need to use CAP_NET_ADMIN privileges and instead the

e436bbf3bb build: Install libfdt in github cross-build workflow
In AArch64 prototype, there are code to construct the flattened device
tree, and to make such code compilable we need to install libfdt-dev. In
normal situation, this installation process can be done by either installing
libfdt-dev locally or in the development container.

Before formal AArch64 CI is setup, we use the workaround in this commit
to install libfdt in the github cross-build workflow.

20cf21cd9d vmm: Change booting process to cover AArch64 requirements
Between X86 and AArch64, there is some difference in booting a VM:
- X86_64 can setup IOAPIC before creating any VCPU.
- AArch64 have to create VCPU's before creating GIC.

The old process is:
1. load_kernel()
    load kernel binary
    configure system
2. activate_vcpus()
    create & start VCPU's

So we need to separate "activate_vcpus" into "create_vcpus" and
"activate_vcpus" (to start vcpus only). Setup GIC and create FDT
between the 2 steps.

The new procedure is:
1. load_kernel()
    load kernel binary
    (X86_64) configure system
2. create VCPU's
3. (AArch64) setup GIC
4. (AArch64) configure system
5. start VCPU's

This causes problems with VIRTIO_RING_F_EVENT_IDX interrupt suppression

always interrupt the guest until the device itself has been signalled by
