'-Wunused-but-set-variable' triggers this warning:
arch/x86/events/amd/core.c: In function amd_pmu_handle_irq:
arch/x86/events/amd/core.c:656:6: warning: variable active set but not used [-Wunused-but-set-variable]
GCC is right, 'active' is not used anymore.
This variable was introduced earlier this year and then removed in:
df4d29732f perf/x86/amd: Change/fix NMI latency mitigation to use a timestamp
[ mingo: Improved the changelog, fixed build warning caused by this fix, improved surrounding code. ]

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.
