WARN if the static keys used to track if any vCPU has disabled its APIC are left elevated at module exit. Unlike the underflow case, nothing in the static key infrastructure will complain if a key is left elevated, and because an elevated key only affects performance, nothing in KVM will fail if either key is improperly incremented.

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 Restructured Text 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.
