commit6c41468c7cupstream. When injecting an exception into a vCPU in Real Mode, suppress the error code by clearing the flag that tracks whether the error code is valid, not by clearing the error code itself. The "typo" was introduced by recent fix for SVM's funky Paged Real Mode. Opportunistically hoist the logic above the tracepoint so that the trace is coherent with respect to what is actually injected (this was also the behavior prior to the buggy commit). 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.
