Paolo Bonzini f144c49e8c KVM: x86: synthesize CPUID leaf 0x80000021h if useful 
Guests X86_BUG_NULL_SEG if and only if the host has them.  Use the info
from static_cpu_has_bug to form the 0x80000021 CPUID leaf that was
defined for Zen3.  Userspace can then set the bit even on older CPUs
that do not have the bug, such as Zen2.

Do the same for X86_FEATURE_LFENCE_RDTSC as well, since various processors
have had very different ways of detecting it and not all of them are
available to userspace.

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.
