Sean Christopherson 80962ec912 KVM: nVMX: Do not report error code when synthesizing VM-Exit from Real Mode
Don't report an error code to L1 when synthesizing a nested VM-Exit and
L2 is in Real Mode.  Per Intel's SDM, regarding the error code valid bit:

  This bit is always 0 if the VM exit occurred while the logical processor
  was in real-address mode (CR0.PE=0).

The bug was introduced by a recent fix for AMD's Paged Real Mode, which
moved the error code suppression from the common "queue exception" path
to the "inject exception" path, but missed VMX's "synthesize VM-Exit"
path.

Fixes: b97f074583 ("KVM: x86: determine if an exception has an error code only when injecting it.")

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.
