Linux kernel source tree
cc7a3393f2
Switch ICL to use a revid->stepping table as we're trying to do on all platforms going forward. While we're at it, let's include some additional steppings that have popped up, even if we don't yet have any workarounds tied to those steppings (we probably need to audit our workaround list soon to see if any of the bounds have moved or if new workarounds have appeared). Note that the current bspec table is missing information about how to map PCI revision ID to GT/display steppings; it only provides an SoC stepping. The mapping to GT/display steppings (which aren't always the same as the SoC stepping) used to be in the bspec, but was apparently dropped during an update in Nov 2019; I've made my changes here based on an older bspec snapshot that still had the necessary information. We've requested that the missing information be restored. I'm only including the production revids in the table here since we're past the point at which we usually stop trying to support pre-production hardware. An appropriate check is added to intel_detect_preproduction_hw() to print an error and taint the kernel just in case someone still tries to load the driver on old pre-production hardware. v2: - Drop pre-production steppings and add error/taint at startup when loading on pre-production hardware.

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.
