There was a specific SW workaround requested, which should prevent
some watermark issues happening, which requires copying highest
enabled wm level to those disabled wm levels(bit 31 is of course
still needs to be cleared).
This is related to different subsystems like PSR and others, which
may still consult a low power wm values ocassionally, despite those
are disabled. For that reason we need to keep sane values in
correspondent registers, even when those are disabled.

v2: Remove redundant WA for ICL and extend this WA for all platforms
starting from SKL, as it seems that we needed this anyway on
all of those(Ville Syrjälä)

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.
