Rather than hardcode the CPU status for all the CPUs instead query from
the CPU manager via the I/O port that is is on via the ACPI tables.
Each CPU device has a _STA method that calls into the CSTA method which
reads and writes the I/O ports via the PRST field which exposes the I/O
port through and OpRegion.
As we only support boot CPUS report that all the CPUs are enabled for
now.

The Linux kernel expects all CPUs, whether they be enabled or disabled
to have an _MAT entry containing the LAPIC details for this CPU with the
enabled bit set to 1 (in the flags.)
In the MADT table the same bit is used to determine if the CPU is
present at boot vs available later.

We disabled msi/msix twice inside Drop trait for VfioPciDevice,

this error by check whether the msi/msix capability is enabled.

The comments of vfio kernel module said that individual subindex
interrupts can be disabled using the -1 value for DATA_EVENTFD or
the index can be disabled as a whole with:
flags = (DATA_NONE|ACTION_TRIGGER), count = 0.

This commit introduces a dedicated document describing the device model
supported by cloud-hypervisor VMM.
It needs to be updated anytime a new device will be added in the future.

When adding devices to the guest, and populating the device model, we
should prefix the routines with add_. When we're just creating the
device objects but not yet adding them we use make_.

The cloud-hypervisor supports the DAX shared region for better virtio-fs

The new micro_http package provides a built-in HttpServer wrapper for

Switching to this implementation allows us to, among other things,

Remove ACPI table creation from arch crate to the vmm crate simplifying
arch::configure_system()
GuestAddress(0) is used to mean no RSDP table rather than adding
complexity with a conditional argument or an Option type as it will
evaluate to a zero value which would be the default anyway.

Create a vhost-user-blk backend using vhost-user-backend and following
the conventions established by the existing vhost-user-net
implementation.
This backend is based on https://github.com/slp/vhost-user-backend,
but a bit simplified, making it closer to the original implementation
in Firecracker. The main features missing are EVENT_IDX, support for
asynchronous I/O and multiqueue, but it's still fully functional and
provides a good starting point for evolving it into a more complete
implementation.
