Set the cache-line-size parameter of the L2 cache for each core to the
correct value of 64 bytes.
Previously, the L2 cache line size was incorrectly set to 128 bytes
for the Broadcom BCM2712. This causes validation tests for the
Performance Application Programming Interface (PAPI) tool to fail as
they depend on sysfs accurately reporting cache line sizes.
The correct value of 64 bytes is stated in the official documentation of
the ARM Cortex A-72, which is linked in the comments of
arm64/boot/dts/broadcom/bcm2712.dtsi as the source for cache-line-size.

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 reStructuredText 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.
