Paulo Zanoni ee435831ec drm/i915/icl: account for context save/restore removed bits
The RS_CTX_ENABLE and CTX_SAVE_INHIBIT bits are not present on ICL
anymore, but we still try to set them and then check them with
GEM_BUG_ON, resulting in a BUG() call. The bug can be reproduced by
igt/drv_selftest/live_hangcheck/others-priority and our CI was able
to catch it.

It is worth noticing that commit 05f0addd9b ("drm/i915/icl: Enhanced
execution list support") already tried to avoid the save bits
on ICL, but only inside populate_lr_context().

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
