[Why] When diags adds a DWB via a stream update, we calculate MMHUBBUB paramaters, but dc->current_state has not yet been updated when the DWB programming happens. This leads to overflow on high bandwidth tests since the incorrect MMHUBBUB arbitration parameters are programmed. [How] Pass the updated context down to the (enable|update)_writeback functions so that they can use the correct watermarks when programming MMHUBBUB.

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.
