Sean Christopherson f27ad73a6e KVM: VMX: Use accessor to read vmcs.INTR_INFO when handling exception
Use vmx_get_intr_info() when grabbing the cached vmcs.INTR_INFO in
handle_exception_nmi() to ensure the cache isn't stale.  Bypassing the
caching accessor doesn't cause any known issues as the cache is always
refreshed by handle_exception_nmi_irqoff(), but the whole point of
adding the proper caching mechanism was to avoid such dependencies.

README

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.
