KVM maintains a mask of supported CPUs when a vPMU type is explicitly selected by userspace and is used to reject any attempt to run the vCPU on an unsupported CPU. This is great, but we're still beholden to the default behavior where vCPUs can be scheduled anywhere and guest counters may silently stop working. Avoid confusing the next poor sod to look at this code and document the intended behavior.

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.
