c22c4675b3 arch, hypervisor: Populate CPUID leaf 0x4000_0010 (TSC frequency)
This hypervisor leaf includes details of the TSC frequency if that is
available from KVM. This can be used to efficiently calculate time
passed when there is an invariant TSC.

TEST=Run `cpuid` in the guest and observe the frequency populated.

Fixes: #5178

4a51a6615f arch: Fix AArch64 socket setting in CPU topology
Before Linux v6.0, AArch64 didn't support "socket" in "cpu-map"
(CPU topology) of FDT.

We found that clusters can be used in the same way of sockets. That is
the way we implemented the socket settings in Cloud Hypervisor. But in
fact it was a bug.

Linux commit 26a2b7 fixed the mistake. So the cluster nodes can no
longer act as sockets. And in a following commit dea8c0, sockets were
supported.

This patch fixed the way to configure sockets. In each socket, a default
cluster was added to contain all the cores, because cluster layer is
mandatory in CPU topology on AArch64.

This fix will break the socket settings on the guests where the kernel
version is lower than v6.0. In that case, if socket number is set to
more than 1, the kernel will treat that as FDT mistake and all the CPUs
will be put in single cluster of single socket.

The patch only impacts the case of using FDT, not ACPI.

0489b6314e tdx: Support new way of declaring memory resources
Without breaking the former way of declaring them. This is simply based
on the presence of the GUID TDX Metadata offset. If not present, we
consider the firmware is quite old and therefore we fallback onto the
previous way to expose memory resources.

4f3f36fe5f tdx: Add support for new method of TDVF descriptor discovery
The preferred way of retrieving the offset where to find the TDVF
descriptor structure is by going through a table of GUIDs that can be
found at a specific offset in the firmware file. If the expected GUIDs
can't be found, we can fallback onto the former way, which is to read
directly the value at a specific offset in the file.

This patch implements the new mechanism without breaking compatibility
for older firmwares as it keeps supporting the previous mechanism.

As a reference, here is the documentation from the EDK2 code, and
particularly from the OvmfPkg/ResetVector/Ia16/ResetVectorVtf0.asm file:

```
GUIDed structure.  To traverse this you should first verify the
presence of the table footer guid
(96b582de-1fb2-45f7-baea-a366c55a082d) at 0xffffffd0.  If that
is found, the two bytes at 0xffffffce are the entire table length.

The table is composed of structures with the form:

Data (arbitrary bytes identified by guid)
length from start of data to end of guid (2 bytes)
guid (16 bytes)

so work back from the footer using the length to traverse until you
either find the guid you're looking for or run off the beginning of
the table.
```

7c3110e6d5 arch: x86_64: Use host cpuid information for L2 cache for older KVM
If the KVM version is too old (pre Linux 5.7) then fetch the CPUID
information from the host and use that in the guest. We prefer the KVM
version over the host version as that would use the CPUID for the
running CPU vs the CPU that runs this code which might be different due
to a hybrid topology.

0522e40933 vmm: Implement translate_gva on AArch64
On AArch64, `translate_gva` API is not provided by KVM. We implemented
it in VMM by walking through translation tables.

Address translation is big topic, here we only focus the scenario that
happens in VMM while debugging kernel. This `translate_gva`
implementation is restricted to:
 - Exception Level 1
 - Translate high address range only (kernel space)

This implementation supports following Arm-v8a features related to
address translation:
 - FEAT_LPA
 - FEAT_LVA
 - FEAT_LPA2

The implementation supports page sizes of 4KiB, 16KiB and 64KiB.
