Tom Lendacky f655e6e6b9 x86/cpu/AMD: Make the microcode level available earlier in the boot
Move the setting of the cpuinfo_x86.microcode field from amd_init() to
early_amd_init() so that it is available earlier in the boot process. This
avoids having to read MSR_AMD64_PATCH_LEVEL directly during early boot.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
