Borislav Petkov (AMD) c809b0d0e5 x86/microcode/AMD: Flush patch buffer mapping after application
Due to specific requirements while applying microcode patches on Zen1
and 2, the patch buffer mapping needs to be flushed from the TLB after
application. Do so.

If not, unnecessary and unnatural delays happen in the boot process.

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.
