Destroying TDX guest requires there's at least one cpu online for each package, because reclaiming the TDX KeyID of the guest (as part of the teardown process) requires to call some SEAMCALL (on any cpu) on all packages. Do not offline the last cpu of one package when there's any TDX guest running, otherwise KVM may not be able to teardown TDX guest resulting in leaking of TDX KeyID and other resources like TDX guest control structure pages. Implement the TDX version 'offline_cpu()' to prevent the cpu from going offline if it is the last cpu on the package.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
