6f4d82bd61 hypervisor: Add support for registering GHCB GPA with hypervisor 
SEV-SNP guest allocates a GHCB page and in order to update hypervisor
about the same, there is a vmgexit which allows registering GHCB page
with the hypervisor.

437e6088e6 hypervisor: Add support for handling VMGEXIT for SEV-SNP guest 
A VMGEXIT exit occurs for any of the listed NAE events in the GHCB
specification [1] (e.g. CPUID, RDMSR/WRMSR, MMIO, port IO, etc.). Some
of these events are handled by hypervisor while other are handled by
VMM. Currently, we are adding support for one such request i.e.,
report supported SEV-SNP features by hypervisor.

1afac185ff hypervisor: Enable VMGEXIT offload for SEV-SNP partition 
For a SEV-SNP enabled partition on MSHV, some of the VMGEXITS are
offloaded for Hypervisor to handle while the rest are handled by VMM.
By setting this additional partition property hypervisor is informed
about the VMGEXITs it needs to take care off, rest all would be handled
by the CloudHypervisor.

b6d009830d hypervisor: x86: Emulator is only needed on mshv, not kvm 
On x86-64, when the underlying hypervisor platform is KVM, no
instruction emulator is necessary. KVM handles instruction boundaries
internally.

This change allows to skip the iced-x86 dependency on KVM, improving
build times, prunes the dependency graph and reduces network traffic
during the initial build.

For Hyper-V, the emulator is still necessary on x86-64, so nothing
changes there.

CpuManager::init_pmu already has a fallback for if PMU is not
supported by the VCPU, but we weren't getting that far, because we
would always try to initialise the VCPU with KVM_ARM_VCPU_PMU_V3, and
then bail when it returned with EINVAL.

dependency via --extern.  This causes a compiler error if using a

it's referring to the module, or the extern version of the crate, so
it's necessary to disambiguate when using the hypervisor module here.

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.

69e8f60b91 tdx: Set the SEPT_VE_DISABLE attribute 
This is required for booting Linux:

From: https://lore.kernel.org/all/20221028141220.29217-3-kirill.shutemov@linux.intel.com/

"""

Virtualization Exceptions (#VE) are delivered to TDX guests due to
specific guest actions such as using specific instructions or accessing
a specific MSR.

Notable reason for #VE is access to specific guest physical addresses.
It requires special security considerations as it is not fully in
control of the guest kernel. VMM can remove a page from EPT page table
and trigger #VE on access.

The primary use-case for #VE on a memory access is MMIO: VMM removes
page from EPT to trigger exception in the guest which allows guest to
emulate MMIO with hypercalls.

MMIO only happens on shared memory. All conventional kernel memory is
private. This includes everything from kernel stacks to kernel text.

Handling exceptions on arbitrary accesses to kernel memory is
essentially impossible as handling #VE may require access to memory
that also triggers the exception.

TDX module provides mechanism to disable #VE delivery on access to
private memory. If SEPT_VE_DISABLE TD attribute is set, private EPT
violation will not be reflected to the guest as #VE, but will trigger
exit to VMM.

Make sure the attribute is set by VMM. Panic otherwise.

There's small window during the boot before the check where kernel has
early #VE handler. But the handler is only for port I/O and panic as
soon as it sees any other #VE reason.

SEPT_VE_DISABLE makes SEPT violation unrecoverable and terminating the
TD is the only option.

Kernel has no legitimate use-cases for #VE on private memory. It is
either a guest kernel bug (like access of unaccepted memory) or
malicious/buggy VMM that removes guest page that is still in use.

In both cases terminating TD is the right thing to do.

"""

With this change Cloud Hypervisor can boot the current Linux guest
kernel.
