David Kaplan 53aa2e9ef3 x86/bugs: Qualify RETBLEED_INTEL_MSG 
[ Upstream commit 204ced4108 ]

When retbleed mitigation is disabled, the kernel already prints an info
message that the system is vulnerable.  Recent code restructuring also
inadvertently led to RETBLEED_INTEL_MSG being printed as an error, which is
unnecessary as retbleed mitigation was already explicitly disabled (by config
option, cmdline, etc.).

Qualify this print statement so the warning is not printed unless an actual
retbleed mitigation was selected and is being disabled due to incompatibility
with spectre_v2.

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 reStructuredText 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.
