Some existing metrics for Neoverse N3 and V3 expressions use CPU_CYCLE to represent the number of cycles, but this is incorrect. The correct event to use is CPU_CYCLES. I encountered this issue while working on a patch to add pmu events for Cortex A720 and A520 by reusing the existing patch for Neoverse N3 and V3 by James Clark [1] and my check script [2] reported this issue.

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.
