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

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.

05e5106b9b hypervisor x86: provide a generic LapicState structure 
This requires making get/set_lapic_reg part of the type.

For the moment we cannot provide a default variant for the new type,
because picking one will be wrong for the other hypervisor, so I just
drop the test cases that requires LapicState::default().

45fbf840db hypervisor, vmm: move away from CpuId type 
CpuId is an alias type for the flexible array structure type over
CpuIdEntry. The type itself and the type of the element in the array
portion are tied to the underlying hypervisor.

Switch to using CpuIdEntry slice or vector directly. The construction of
CpuId type is left to hypervisors.

This allows us to decouple CpuIdEntry from hypervisors more easily.

No functional change intended.
