Intercept CR4 bits that are guest reserved so that KVM correctly injects a #GP fault if the guest attempts to set a reserved bit. If a feature is supported by the CPU but is not exposed to the guest, and its associated CR4 bit is not intercepted by KVM by default, then KVM will fail to inject a #GP if the guest sets the CR4 bit without triggering an exit, e.g. by toggling only the bit in question. Note, KVM doesn't give the guest direct access to any CR4 bits that are also dependent on guest CPUID. Yet.

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.
