Recompute the entire set of supported VM types when a vendor module is
loaded, as preserving supported_vm_types across vendor module unload and
reload can result in VM types being incorrectly treated as supported.
E.g. if a vendor module is loaded with TDP enabled, unloaded, and then
reloaded with TDP disabled, KVM_X86_SW_PROTECTED_VM will be incorrectly
retained. Ditto for SEV_VM and SEV_ES_VM and their respective module
params in kvm-amd.ko.

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.
