The PL310 Auxiliary Control Register shouldn't have the "Full line of zero" optimization bit being set before L2 cache is enabled. The L2X0 driver takes care of enabling the optimization by itself. This patch fixes a noisy error message on Tegra20 and Tegra30 telling that cache optimization is erroneously enabled without enabling it for the CPU: L2C-310: enabling full line of zeros but not enabled in Cortex-A9 Cc: <stable@vger.kernel.org> Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Tested-by: Nicolas Chauvet <kwizart@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
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.
