Explicit management of the GPU's core stacks is only necessary in the case of a broken integration with the PDC. Since there are no known platforms which have such a broken integration let's remove the explicit control from the driver since this apparently causes problems on other platforms and will have a small performance penality. The out of tree mali_kbase driver contains this text regarding controlling the core stack (CONFIGMALI_CORESTACK): Enabling this feature on supported GPUs will let the driver powering on/off the GPU core stack independently without involving the Power Domain Controller. This should only be enabled on platforms which integration of the PDC to the Mali GPU is known to be problematic. This feature is currently only supported on t-Six and t-HEx GPUs. If unsure, say N.

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.
