Sean Christopherson d38ea9579c KVM: x86: Bug the VM on an out-of-bounds data read
Bug the VM and terminate emulation if an out-of-bounds read into the
emulator's data cache occurs.  Knowingly contuining on all but guarantees
that KVM will overwrite random kernel data, which is far, far worse than
killing the VM.

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.
