755cabea4c hypervisor: use proper doc tests for examples
It seems like these examples were always intended to be doctests,
since there are lines marked with "#" so that they are excluded from
the generated documentation, but they were not recognised as doc tests
because they were not formatted correctly.

The code needed some adjustments so that it would actually compile and
run as doctests.

1ed4898d28 hypervisor: fix building doctests
When doctests are built, the crate is built with itself as a
dependency via --extern.  This causes a compiler error if using a
module with the name same as the crate, because it's ambiguous whether
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.

Fixes running cargo test --doc --workspace.

57ea412c64 hypervisor: make buildable independently
It was not possible to build just hypervisor with Cargo's -p flag,

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.
