Peter Zijlstra 2edfa537f3 x86/common: Stamp out the stepping madness
commit 7a05bc95ed1c5a59e47aaade9fb4083c27de9e62 upstream.

The whole MMIO/RETBLEED enumeration went overboard on steppings. Get
rid of all that and simply use ANY.

If a future stepping of these models would not be affected, it had
better set the relevant ARCH_CAP_$FOO_NO bit in
IA32_ARCH_CAPABILITIES.

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.
