Set EDX at RESET/INIT based on the userspace-defined CPUID model when
possible, i.e. when CPUID.0x1.EAX is defind by userspace. At RESET/INIT,
all CPUs that support CPUID set EDX to the FMS enumerated in
CPUID.0x1.EAX. If no CPUID match is found, fall back to KVM's default
of 0x600 (Family '6'), which is the least awful approximation of KVM's
virtual CPU model.

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.
