IFS is a CPU feature that allows a binary blob, similar to microcode, to be loaded and consumed to perform low level validation of CPU circuitry. In fact, it carries the same Processor Signature (family/model/stepping) details that are contained in Intel microcode blobs. In support of an IFS driver to trigger loading, validation, and running of these tests blobs, make the functionality of cpu_signatures_match() and collect_cpu_info_early() available outside of the microcode driver. Add an "intel_" prefix and drop the "_early" suffix from collect_cpu_info_early() and EXPORT_SYMBOL_GPL() it. Add declaration to x86 <asm/cpu.h> Make cpu_signatures_match() an inline function in x86 <asm/cpu.h>, and also give it an "intel_" prefix. No functional change intended.

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.
