While doing a quick sanity check of the ICL workarounds in the driver I noticed a few things that should be updated: * There's no mention in the bspec that WaPipelineFlushCoherentLines is needed on gen11 (both the current WA database and the old, deprecated page 20196 were checked); it appears this might have just been copied from the gen9 list? Even if this were needed, it doesn't seem like this was the correct implementation anyway since the gen9 workaround is supposed to be implemented in the indirect context bb (as we do in gen8_emit_flush_coherentl3_wa() on gen8/gen9). * WaForwardProgressSoftReset does not appear in the current workaround database. The old deprecated workaround list has a note indicating the workaround was dropped in 2017, so we should be safe to drop it from the code too. While we're at it, add the formal workaround ID number to WaDisableBankHangMode (our hardware team made a transition from text-based workaround names to ID numbers partway through the development of ICL, which is why some workarounds only have names, some only have numbers, and some have both).

README
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.
