Right now context workarounds don't do a rmw and instead only write to the register. Since 2 separate programmings to the same register are coalesced into a single write, this is not problematic for GEN12_FF_MODE2 since both TDS and GS timer are going to be written together and the other remaining bits be zeroed. However in order to fix other workarounds that may want to preserve the unrelated bits in the same register, context workarounds need to be changed to a rmw. To prepare for that, move the programming of GEN12_FF_MODE2 to a single place so the value passed for "clear" can be all the bits. Otherwise the second workaround would be dropped as it'd be detected as overwriting a previously programmed workaround.

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.
